When Li Xiangping went downstairs, he saw his old man calling and speaking in his hometown dialect, Li Xiangping guessed that he was probably calling to his hometown.

When Li Datuo hung up the phone, Li Xiangping asked casually:

"How is it, are grandparents okay?"

Li Datuhao said: "Your grandparents are fine. It's just that the weather is a bit weird. Ice disaster? There will be a large-scale ice disaster in my hometown?"

Li Datuhao shook his head and continued, "I heard from my grandfather that the large area of ​​wind and snow have affected the power supply. Now the power outage at home is coming every few days. Oh, it's really evil."

After Li Datuo sighed, he did not talk much with Li Xiangping.-----The shopping mall in Jianguomen has opened and the business is so good that it is full of money. Li Datuo was busy counting money, so he hurried out, leaving Li Xiangping alone in a daze.

Li Xiangping was really dazed. To be honest, the abnormal weather is nothing at the moment. This kind of disaster will at most cause some inconvenience in life and some economic losses. Li Xiangping did not take this kind of thing seriously. The reason why he was dazed was mainly because from this incident, he soon thought of the earthquake that occurred in Chuansheng three months later in real history, which was a catastrophe that was at stake in life.

"Oh, I am a time traveler, so why don't I prevent this in advance like many time travel seniors..."

However, Li Xiangping was relieved quickly. After all, this kind of thing cannot be prevented just by wanting to prevent it. Humans are actually powerless to face the power of nature, even if Li Xiangping is a time traveler.

And this sense of powerlessness is actually far beyond that of human professional chess players when facing Go AI.

First of all, Li Xiangping cannot issue a preview for such things in advance----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If Li Xiangping believes that if he dares to do this, someone will come to check the water meter soon. The hat of "spreading rumors and creating social panic" will definitely not be able to escape.

Then at that time, no matter how good I play Go, I will not be able to save me.

Secondly, as a online literary enthusiast, Li Xiangping often sees many time travel seniors doing this, especially in 2008, who always wanted to play the role of the savior in the face of that great disaster. However, to be honest, even if Li Xiangping is just a half-baked civilian dog, with his pitifully few professional knowledge, he also knows that most of the methods of time travel seniors are not reliable.

To give a simple example, most people don’t know how earthquakes cause damage, and they don’t know how to prevent earthquakes.

It is precisely because of this that when most time travel seniors write about the relevant plot, Li Datuhao's construction colleagues will definitely be scolded. Most time travel seniors will scold them for cutting corners, doing shoddy projects, and then adding steel bars and cement according to their own imagination, and building houses with high earthquake resistance levels according to their own imagination.

Well, Li Xiangping, a half-baked native dog, can tell everyone very responsibly that if anyone really does this, not only will it not be able to increase the intensity of earthquake resistance, but even when a large earthquake of magnitude such as Sichuan comes, this approach will most likely cause greater damage.

Because earthquakes are different from wars, if you want to defend against an explosive pack and build a solid bunker, then your method is still feasible.

However, earthquakes are not explosives, they cause harm to humans with earthquake waves, so this kind of damage has two important characteristics;

First, seismic waves do not cause direct damage. Usually secondary disasters are caused by seismic waves, such as landslides, earth cracks, and tsunamis, which cause harm to humans.

Second, the time of each seismic wave is actually very short, usually only a few seconds, and most of them end within one or two seconds.

It is precisely because of this that the method of adding steel bars and cement is not good. This method not only has poor results, but also can easily cause greater casualties when it really causes secondary disasters------

Let me give you a very simple example. If a house collapses due to an earthquake, will it be easier for reinforced concrete to hurt people, or will wooden pillars or even lighter materials such as carbon fiber materials be more likely to hurt people?

So what is the most correct method of anti-seismicity?

Li Xiangping remembers that just 10 years ago, a foreign architectural structure engineer once conducted an experiment:

He made a model of a palace in the Forbidden City, and restored the model according to the reduction ratio standard of 1 to 10 or 1 to 5, and then used such a model to perform earthquake resistance experiments.

As we all know, the palaces in the Forbidden City are all wooden buildings, and this type of ancient Chinese buildings actually has another characteristic, that is, the foundation is very shallow. Even the royal buildings in the Forbidden City, most of the pillars will not exceed one meter.

Well, as the saying goes, the foundation is not solid, and the earth is shaking. I believe that in everyone's impression of being taken for granted, this type of building must be earthquake-resistant, right?

But what were the results of that experiment?

Simulate the earthquake intensity to magnitude 7, and the model is unscathed.

When the earthquake intensity was increased to 8, some wall panels of that model fell off, but the overall structure was still safe.

Finally, the foreign structor used his big move and directly simulated the earthquake of magnitude 9. As a result, the wall panels of the model were almost completely shaken off, but the entire house still did not collapse.

This is the famous "walls falling down and the houses don't collapse" experiment in the architectural industry.

It is precisely because of this experiment that the two seismic resistance methods that have been long-disputed in the academic community (the one that "adds steel bars and cement" is called rigid seismic resistance, and the one that comes later is called flexible seismic resistance). The flexible seismic resistance method has gained a decisive advantage. Almost all important large buildings in later generations are mainly flexible seismic resistance, supplemented by necessary rigid seismic resistance methods.

For example, in later generations, our country's Hong Kong-Zhuhai-Macao Bridge, Daxing International Airport, etc. were basically flexible and earthquake-resistant.

As long as this method is good, as non-professionals, you don’t need to understand it in detail. Simply put, the principle of flexible earthquake resistance is actually a bit like a fence------

When you have a level 12 typhoon, those big trees that seem to be deep in the roots may be uprooted, but what if you are a fence-bearing plant? It is likely that you will be completely unharmed.

And this is actually basically the same as the principle of flexible earthquake resistance.

"Oh, it seems that by that time, I can only donate more money. After all, I am a wasteful time traveler. Apart from knowing how to play Go, I only have a few bad money left. I just hope that those time travelers or juniors will not laugh at me..."

After posting this at home, Li Xiangping quickly calmed down and prepared for the next game.

The "LG Cup" final with Xiao Li was held from February 3 to 6. At this time, the school was on holiday. Considering that the old man would not go home during holidays, the old man would have an objection, so Li Xiangping has been staying at home these days.

Of course, there is one thing that is not good at staying at home, that is, it is not free enough. Especially for people like Li Xiangping who have a girlfriend, their home is definitely not as convenient as the apartment outside.

When she finished thinking about the earthquake, Li Xiangping remembered that Yaya is already a senior year this year and she is about to graduate in only one semester. She seems to be facing a problem of going to the place after graduation.

Well, if it were Li Xiangping himself, of course he wouldn't consider such things. For example, he would soon become a junior, but he would basically not consider where he would go after graduation from Peking University. Anyway, he had already thought about it. Before fighting dogs, he would definitely not leave Go. Even if he wanted to start a so-called new life, he had to talk about it after fighting dogs.

But of course her girlfriend Yaya is different. She can't say that she will become an unemployed vagrant after graduating from the Central Academy of Drama. Therefore, when she remembered this, Li Xiangping decided to call a few more times before asking.

Li Xiangping thought about it, picked up the phone and dialed it to Yaya, asking her to clean up first, and take her to a place to have dinner in the evening.

After hanging up the phone, Li Xiangping called Zhao Daokai's father Zhao Jiadong again.

"Haha Xiangping? Why did you, the big chess saint, call me?"

Li Xiangping smiled and said, "Uncle Zhao, don't get me wrong. I don't miss you, I miss your cooking skills. You haven't had a social engagement at night, are you going to take someone to your house for free."

Zhao Jiadong quickly grasped the point: "Take someone, who will I bring?"

There is no need to beat the relationship between the two families around the bush. Li Xiangping said bluntly: "Yaya."

"Hehe, you boy," Zhao Jiadong smiled from the other end of the phone:

"If you want to come here, just get up early. Your Aunt Liao just came back from a business trip yesterday. I'll call her to buy vegetables now."

In the evening, Li Xiangping led Yaya to Zhao Jiadong's house. At the door of the house, he happened to meet Zhao Daokai's mother, Aunt Liao, the top academic and scientific and technological woman from the Chinese Academy of Sciences.

But even a top student and a science and engineering girl can gossip. Aunt Liao smiled as soon as she saw the two of them, and saw her looking up and down at Yaya:

"Haha Xiangping, this should be Yaya, she looks so handsome. Well, you were all gossiping about you some time ago, and even I was confused. Which one is the real one..."

Li Xiangping quickly interrupted her: "Haha, then you know now."

"Hehe knows, come, come, come in quickly."
