Chapter 604

Chen Xin is also very concerned about the ongoing national geological survey.

After all, there is still a way to overcome the cold environment, but if there is something wrong with the earth under your feet, you will really lose your home and shelter.

So far, however, the results are worrying.

The impact of the eruption of DOPA volcano is global, and the whole blue star will be affected by it.

It's not just that volcanic ash covers the world and earthquakes hit the southwest.

This is a super volcano, its eruption can even create a species extinction, let the whole blue star into disaster and havoc.

Although it is not the disaster of mass extinction and global large-scale geological changes as the geological dating, the consequences of super volcano eruption can not be underestimated.

After all, such a terrible eruption will have a great impact on the plate movement and crustal activity of the whole blue star.

Especially before that, there were enough meteorites to break through the earth's crust and fall down. Now is the time to show its impact on blue stars.

In fact, the national geological survey of major cities in the country also proves this to a great extent.

Geological activities all over the country tend to become active. Although small-scale earthquakes will not bring any impact, no one can guarantee that with the active geological activities, large-scale earthquakes will not occur.

Fortunately, at present, the major cities in China are not in the areas with extremely active geology. After all, it is difficult to form big cities in such areas. In ancient times, people would spontaneously avoid such dangerous areas.

So up to now, the main geological problems found are the subsequent secondary disasters caused by earthquakes, such as cracks, collapses, groundwater level decline and other problems that are not fatal but still troublesome to deal with.

At present, the geological survey plan is still in progress. According to the national meaning, it means to conduct a survey in the main areas of the country. At present, only the screening of major cities has been completed.

Although many problems have been found, the good news is that so far, there is no sign of disaster of the same magnitude as the previous earthquake in Southwest China.

Moreover, due to the influence of environmental factors, some possible geological disasters such as landslides have been eliminated, only avalanches occurred in some areas.

Although avalanches are also terrible disasters, they are nothing compared with landslides or other geological disasters.

However, although these geological disasters are not fatal, they also make the current environment worse.

Apart from other things, because of the earthquake, the groundwater level in many areas has been affected, the water level has dropped, the incoming water has not been available, or the water quality has become turbid due to the earthquake, which will have a great impact on people's lives.

Although small-scale earthquakes in some areas will not pose any threat to cities and refuges, mines can not withstand such small earthquakes.

We should know that the mine itself is destroying the geological structure. Although the development of modern mining technology makes the mine safer, it does not mean that it is really safe.

Otherwise, before the disaster, there would be no news of mine accidents every year.

As for the impact of geological disasters on engineering construction, not to mention that, according to the information Chen Yu received, a lot of construction projects were affected by geological disasters, which affected the construction period, and individual projects even had to be relocated.

On the other hand, because of the large-scale geological collapse and the decline of groundwater level in the urban area, Chen Xin, who originally planned to choose the first dome city here, had to change his mind and consider choosing an area with more stable geological conditions.

We should know that this area at the junction of Hunan Province and Hubei Province is not only mountainous, but also an area where geological activities were active or the stratum was thin. Otherwise, there would not be so many hot springs underground.

Now, affected by the previous events, the local geological activities have become active, but it is not conducive to the site selection of the new town.

In fact, there are many mountains in Hunan Province, but there are not many relatively plain areas. It is not easy to choose a suitable place to build a dome city.

After all, the diameter of the dome city is only five kilometers, and the whole city is less than a big city. It's a small city, but it's also a city, which will accommodate tens of thousands of people.

In fact, according to the current design, the dome city is expected to accommodate 50000 to 70000 people. If it is crowded, the design will be more compact, and it will not be difficult to accommodate 100000 people.

With such a large population, the state obviously attaches great importance to site selection. If something goes wrong, no one can shoulder the responsibility.

So these days, on the one hand, Chen Xin is paying attention to the design drawings, on the other hand, he is also discussing the problem of site selection with geological experts.

The site selection of this city as a dome city has been abandoned due to geological collapse. After discussing with experts at present, we tend to move the city to the direction of the provincial capital Star City, and build more domes in the future to serve as the new urban area of this city, and simply move this city to its location.

After all, the city was originally located on the Bank of Dongting Lake, which is a very rich area of groundwater network. In ancient times, it was a part of yunmengze. If the groundwater network system was affected by the earthquake, causing a large range of groundwater level decline and geological collapse, the city would also be threatened.

It is a very valuable proposal to move the urban area southward to a more stable area and build a new city.

It's just that the investment and impact are too great. Even if it's just building a dome city now, it's a great project to move a part of the population first, let alone the whole city later.

For the country, even before the disaster, such a thing is not easy to complete, so this plan is only a proposal at present.

However, Chen Xin himself is very interested in the idea of connecting multiple dome cities together to form a whole.

Dome City is only similar to the area of an urban area in the past, even smaller. In this case, a single Dome City obviously can not accommodate the whole population of the next city, even if it is only a small city, and a large number of people have been lost due to the previous disaster.

So the idea of building new domed cities and connecting them to form a new urban area is very creative.
