Chapter 292 Disaster recovery work is launched and the electromagnetic gun is put on the ship!
Just as the heavy-duty helicopter reached a technical cooperation agreement and the Z-30 project was officially launched, on the other side, other disaster preparedness work also began to proceed in an orderly manner.
In Yingxiu County, a special team entered the county town carrying various instruments.
On the surface, they are performing a mineral exploration mission, but in fact, they are trying to explore the main geological structures within a 15-kilometer radius centered on Yingxiu within a month, and select the location of the "seismic shield"
Construction scope.
Near Yingxiu Zuji Ditch, exploration team leader Zheng Jiuyuan took off the heavy equipment on his shoulders, wiped the sweat from his forehead and said:
"It should be right here, 31 degrees north latitude and 103.4 degrees east longitude."
“It’s really rare to find a car with such accurate location.”
"I've definitely never seen it before."
The team member Zhong Jian on the side carefully placed the backpack-type portable drill on the flat ground, and then continued:
"If we go back thirty years, I remember that we were still quite keen on predicting earthquakes at that time, but now, we haven't heard of such a thing for many years."
"If the order hadn't come directly from the working group, I would have thought it was a joke."
Hearing his words, Zheng Jiuyuan nodded slightly.
"It's all the same. As long as they are really doing geological work related to earthquakes, I don't think anyone can believe in earthquake predictions."
"Earthquakes are a typical chaos model, and there is no directly observable indicator system. With our current technical level, even predicting the probability is extremely difficult, let alone accurately predicting the three elements."
"I have always felt that the earthquake in Haicheng was purely an accident that killed the mouse - and there was indeed no successful case in the end."
"But this time, it feels like it's serious."
"How to say?"
Zhong Jian asked curiously.
"Have you read the news? Recently we signed a heavy-duty helicopter import contract with Russia, and the outside world is guessing what these heavy-duty helicopters will be used for."
"Some people speculate that there is a big movement on the border, and some people speculate that it will be deployed to Djibouti in Africa to build armored airborne troops."
"But these people obviously didn't get the idea. If you combine what we are doing now, it is obvious that these helicopters are used for disaster relief."
"This is a large order of nearly 1.5 billion yuan, and the investment is frighteningly high."
"If it is not a certain matter, the official will not take this risk."
Looking at Zheng Jiuyuan's serious expression, Zhong Jian frowned thoughtfully, and then continued to ask:
"What if I just bought it as a casual purchase?"
"What I mean is, maybe the main purpose is military, and it can also be used as a backup."
"But looking at this one thing, it is indeed possible."
Zheng Jiuyuan took a breath and continued:
"But when you watch the news, you have to look at it comprehensively."
"Recently, this is not the only big move taken by the higher authorities."
"Over at the Economic Port, superiors have issued several new notices, requiring some enterprises and institutions to do a good job of 'capacity reserve'. What does this mean? It means that two machines can do the work, but now the number of machines must be increased.
To Taiwan 3.”
"Generally speaking, this kind of notice is issued for only two purposes."
"Either to indirectly stimulate economic growth, or to cope with the impact of major events in the future."
"We don't need economic growth - the current growth rate is fast enough."
"As for major events, in fact, the only major events that can be predicted are wars."
"Do you think it's possible for us to fight? It's impossible."
"So, it can only be a disaster."
Zhong Jian seemed to have been convinced by Zheng Jiuyuan, his expression became solemn, and then he asked:
"So you're saying that this earthquake is really possible?"
"I have no idea."
Zheng Jiuyuan shook his head and continued:
"No one can say for sure whether it will happen, but from a certain perspective, officials have indeed determined that this earthquake will happen."
"So, what we have to do is to keep secrets, use our abilities, and actively cooperate."
"You know, if it didn't happen, that would be a great thing because no one would die."
"If it happens, every minute we spend here, we may save more than one person."
"Then take action quickly."
Zhong Jian immediately stood up and began to assemble the portable drilling instrument quickly.
Two other team members with military backgrounds also stepped forward to assist. It didn't take long for the instrument assembly to be completed, and the two men immediately started drilling operations.
As the soil and rock samples that went deep into the ground were constantly brought out of the ground, Zheng Jiuyuan couldn't help but sigh and said:
"Just looking at the environment of this location, the probability of an earthquake is really high. If it happens, the damage caused will be huge."
"This place itself is located on the thrust nappe tectonic belt. There are three major faults nearby, which are stress concentration points where the two plates are squeezed. The accumulated stress on the nappe tectonic belt is definitely not small. It is normal for earthquakes to occur.
matter."
"Coupled with the complex topography, unstable rock structure, and water and soil erosion here, once an earthquake occurs, a large number of slope instability will definitely occur."
"When the time comes, once secondary disasters such as intensive aftershocks, barrier lakes, and mudslides occur, the intensity of rescue operations will increase exponentially."
"It's no wonder the authorities attach so much importance to it. It's really not a trivial matter."
Hearing his words, Zhong Jian temporarily stopped what he was doing, the roar of the drill became quieter, and he said:
"That has to actually happen. Anyway, I still hope this is just a misjudgment."
"Actually, the probability of misjudgment is quite high, estimated to be over 99%."
"But overall expectations are too high."
Zheng Jiuyuan interrupted him. Zhong Jian was stunned for a moment and then understood what he meant.
With a 100% probability, if the loss multiplied by the indicator is 1, the expectation is nothing more than 1.
But if the probability of 1% is multiplied by the loss indicator of tens of billions, then the expectation will reach an astonishing hundreds of millions.
So, he sighed and said:
"Indeed. So we must do our best."
"But having said that, are earthquake shields really useful? I have never seen any country use this method to prevent earthquakes."
"Useful, and very useful."
Zheng Jiuyuan answered without hesitation.
"The reason why you haven't heard of it is because the construction of the earthquake shield is too difficult and the amount of work is too large, so there is no way to implement it."
"But in fact, if we can delineate a certain area and build a seismic shield structure in advance, like us, it can have a great effect."
"According to theoretical calculations, after combining the two methods of earthquake shield and surface vegetation cloak, earthquake Rayleigh waves can be reduced by at least 70%."
"With this level of attenuation, the destructive effect has been greatly reduced."
"Of course, the main thing we are talking about here is noodles."
"The damage caused by body waves is inevitable no matter what, but compared to Rayleigh waves, body waves are much less destructive, both horizontally and vertically."
"We have no way to eliminate body waves. We can only rely on the strength of the building to deal with them."
Zhong Jian was silent for a moment again, and then continued to ask:
"But the problem is that the transmission of body waves will eventually lead to the formation of surface waves. Even if our earthquake shield surrounds Yingxiu, it is still impossible to block most of the body waves, right?"
"That's why the range is 15 kilometers."
Zheng Jiuyuan explained:
"According to information from superiors, the focal depth of this earthquake is about 14 kilometers. With the source surface as the center and 15 kilometers as the radius, we can attenuate the Rayleigh wave as soon as it is formed."
"However, we are only conducting a preliminary investigation now. Depending on the situation in the future, the radius of the earthquake shield may be extended."
"By that time, the risk will be further reduced."
Zhong Jian nodded heavily and then said:
"It seems that the superiors have thought carefully this time."
"Yes, so we can't make any mistakes in execution."
