High efficiency
We can introduce academician Xie to our class today.
Many of our classmates don't know.
But we have a lot of civil engineering colleagues here who know that our college is now.
Director of the Institute of mechanics of the national seismological Bureau of China
It is professor Bodao of Hangzhou university.
He is the president of China earthquake engineering Federation.
Have been heard comrades fold to a lot of schools to actually speak.
Because the course professor studies the teacher.
Part-time teacher
At the same time, it is also to our Tongji university, the north university of technology.
University of Guangzhou, Tsinghua university, Tianjin university
One who is the honorary director and chairman of the academic committee of the state key laboratory.
Among them is our Tongji university.
Our national key laboratory
After 20 years of being our student back.
So our students at the same college know
But other college students have never had a chance.
Day
Thank you for this lesson.
So in '94
Actually the first academicians of the Chinese Academy of engineering
So from '06 to' 14
Has been the Chinese Academy of engineering organization team.
So back in the '80s
It began in 1987 as an international United nations international by the Secretary-General of the United nations.
Special expert group
That is, the general group of experts are all departments.
This is the United nations Secretary-General's direct feature of the group of experts on historical characteristics.
Also very proud
Is the pride of our China.
A member of one of our experts in the un's top panel of experts on characteristics.
Members of the United nations CST
He was also elected vice president of the international earthquake engineering association.
The chairman of the international strong earthquake society, chin, was organized by the international seismological organization from 1987 to 2001.
Ten selection
Executive chairman of the international society for seismology and geophysics
This position is very important.
Maybe it's clear to a lot of students.
This is the first organization in more than a hundred years.
So far, it is the only one that has an engineer present to do such a project.
Such an important post
Now it is in the main areas of earthquake engineering and safety engineering.
Evaluation of earthquake prevention and anti-earthquake ability in cities
Well, more than 400 articles have been published at home and abroad.
In fact, for me, it is the second day after the Wenchuan earthquake in 2008.
Because of our urban planning professional response to the district.
Also because of Tongji university
We all know that at the most difficult time
It was the English who received us.
After passing the whole great wall, the market has come down greatly.
So the time I worked in Sichuan
A most wanted to read
Especially when looking for that information
Have read many articles of academician Xie
In fact, it is of special concern to us.
In fact, it is now he has put forward a series of engineering very important concepts.
In fact, for us, China and the world's earthquake relief this piece.
Although it is a very important state of an electrical appliance.
Is the concept of innovation.
Very important warranty
Today, this topic is actually in all of us do urban planning, all people do urbanization.
What must be discussed
There seems to be no one who doesn't talk about such an important issue today.
So today is especially important
Our wish is to recover.
What does this person know about the word?
If you didn't learn this
I think we are missing a big piece of this class.
We are talking about the past.
Is to lead us to today in the international dynamic urbanization research, urban research, urban planning.
Research center
The latest eight years
So very happy
I don't spend much time leaving this time to our college.
Is to be able to come first
It is a great honor for all of us.
Because there are really many others
We all know that light school is to meet so many school professors.
That is, there are so many jobs waiting at home and abroad.
Even the very important time between HNA can be invited to our big class.
We welcomed the report of academician Xue with warm applause.
Well
First of all, I would like to thank president Wu for introducing me to you.
I also want to thank president Wu.
I was invited to attend such an important general course.
Thank you very much
I want to thank all of you.
Teachers
You are so busy in a day.
And come and listen to our lessons
Thank you very much
What I want to talk to you about today is civil engineering disaster and the construction of a recoverable disaster prevention.
System
Civil engineering disaster these terms you are not easy to find on the Internet.
May not be found
Because this is our creation
Let's bring it up
Is it right?
Please ask the students and teachers to give more criticism.
Our children's workstation is a very important disaster.
So far, we have not been found and better.
Therefore, it is necessary for us to stress repeatedly the importance of such a disaster to us.
So the English name is siri1.02
The third party is the key.
I would like to draw your attention to these words.
This is recognized as
His name is called out and we will meet again.
Like 0cs
Moore's investors want to build a town that's very much better off.
So there are three purposes of my lecture.
Article 2 the west is very easy to develop in the course of urbanization.
Now urbanization is an important task in our country.
It is very easy to develop the kind that is most closely related to human beings.
It is not known to everyone yet.
And the color that directly affects human security
A disaster called civil engineering
Is it that serious?
Or do I fool you?
Let's look below.
The second point I would like to make is that the letters and visits indicate that there are quite severe natural disasters.
In fact, it was not caused by nature.
But because of our civil engineering
Everybody misunderstood
Recognize their essence
Can effectively reduce natural disasters.
For example, our country often occurred in the world, a frequent earthquake disaster.
Very serious
Are killing hundreds of thousands of people
In the past, it was thought that it was caused by nature.
Earthquake
So it took a lot of effort to do earthquake prediction.
What the hell
In the end, there was little effect.
We found this so-called earthquake disaster.
And wind disasters
There are other nishihon
He was not caused by nature.
It is precisely because of our civil engineering.
What are the reasons for the headquarters work?
As we all know, it is absolutely not natural.
So you know what it is
Can effectively reduce natural disasters.
Including earthquake disasters
Finally, we have to stress through this lecture.
What is the ultimate goal of mitigating and defending civil engineering disasters?
How can we defend ourselves?
It is necessary to establish a town defense system with the function of treating and recovering.
You set up the system
I am not afraid of all the disasters.
Then I need to be clear
This is also the most rational and reform measure to achieve sustainable development.
Everybody knows
We are all talking about sustainable development now.
Our lectures also focus on sustainable development.
What is sustainable development?
How can you do it?
One is loyalty.
The problem has never been solved.
So I want to do society through Jiang Zhikang today.
Be able to make it clear to you
This is the best way to achieve sustainable development.
In fact, completely operational measures.
Is operation a simple concept?
Sustainable development
And there are quantitative indicators
Fully operable
So there are three main elements
The first is the definition of civil engineering disaster.
Origin, characteristics and category
Second
The ultimate goal of mitigating and defending civil engineering disasters is to reduce and build an intelligent rehabilitation capacity.
The town
Third, we should talk about how to build a rehabilitation and prevention system.
How to build
We can't just talk about construction.
Let's talk about it until you feel it's operational.
Let's talk about the first question.
Definition of repeated exposure to disasters
Intergrated category
What is natural disaster?
We hear this term every day.
On TV, on the radio.
The newspaper says about our own rise, and so do I.
But I invite you
What role are you telling me?
Which student raised his hand and said that I could explain the dishes clearly.
Did you eat when we called for dinner every day?
I didn't eat
We talk about disasters every day.
What exactly is disaster?
We can make it clear
Hear
You're finished, aren't you?
Well
Sit down please
So far, there are about two or three hundred definitions of disaster.
But no definition of disaster can be accepted.
As the girl said just now
He also made a definition.
So if it were 205
You are 251
So what is disaster?
I'm trying to make a definition, too.
Take a look at the definition of disaster.
Can we accept it?
We accept
After that, make it clear.
Let me explain a few more elements.
The first factor disaster generally refers to the unexpected sudden event.
If I had known earlier, I could have taken precautions.
You could have kept it from happening
Right
So it's usually an accident.
The second 12 is the result, not the reason.
Is it a disaster that cannot be seen as its cause?
It can't be said that the earthquake caused the disaster.
The disaster is coming
You can't say that
See whether the earthquake has the consequences of the disaster.
So let's take a look at this earth
240 million years ago, the earth has evolved to the present 240 million years.
And let it out in ten seconds
Or you can look at the earth as a whole.
Then it slowly became a lot of plates.
The Indian ocean plate also frequents our western regions.
Southwest corner entry
And it formed our Himalayas and the kangshan plateau
That's how it's formed
One earth is fluctuating
The shock is the inadvertent strong vibration of the earth's crust here.
Cause a strong earthquake
Isn't it
But we know that we are the oldest people on earth, and we can't get old anymore.
That is, two million years of history.
In other words, what does it mean?
I had an earthquake more than 200 million years ago.
Can it cause disaster?
Do not cause disaster
Why is there no consequence?
Therefore, I think the earthquake is not to see whether there are any consequences of the disaster.
It can't be said that an earthquake is a disaster.
Right
I want to make it clear that this problem is not in don't look at it.
It is therefore necessary to see whether the results have consequences or not.
Third
The main attribute of a disaster is that there must be a loss.
No loss, no obstacle
If I earn a little more, I get this kind of harvest.
That must not be called disaster.
Right
In this way, everyone would like to meet you hurt.
Isn't it
So what kind of loss?
The students said just now.
Loss of life or property.
It's not just life and property
What other life and property resources?
It also includes the loss of our ecological environment.
Is the four major categories of losses
Is the category of disaster
But only life and property
Ecological environmental damage rate
Not necessarily make a disaster
For example, we may have more than ten people in traffic accidents every year.
You can say that we have a disaster.
There was a great disaster.
Probably not, is it?
So there's a condition
What conditions must be beyond the carrying capacity of the carrier.
If we had two people killed in a traffic accident.
Both are in the same family.
It's a single for the family.
For society
He can't afford it in society.
Death of two or three people is not such a great disaster.
Isn't it
Therefore, there is a condition beyond the carrying capacity of the carrier.
So there are a few features standing like this
We put it together
We will come to the three rivers to define.
What
Definition
It is called causing loss of human life, property, resources and ecological environment.
And copy an existential capacity
This kind of emergency is called disaster.
So let's see if this definition is perfect.
Unclear
Is there anything wrong with it?
I hope you can find something wrong.
So what is civil engineering disaster?
Very simple
Is a disaster for people caused by civil engineering.
Disaster in government engineering
What is civil engineering?
Cause
Our village is digging down there.
What is civil engineering?
Cause
Let's talk about it later.
The infinite civilization that civil engineering brings to mankind
At the same time, it has brought infinite disaster to mankind.
This is in civil engineering
Our civil engineering is a very great company.
The greatest of all projects
Much greater than space flight
Why
Because for civil engineering to bring us human civilization is the carrier of civilization.
Do you believe it or not?
Since then, it has brought infinite civilization to mankind.
