Yin Yueping first talked about the new problems currently facing.

He said that the earthquake is located near the intersection of the "Y" font structure composed of the three broken belts (Songpan -Longmen Mountain Fracture Belt, Fresh Water River Fracture Belt, and the Anning River -Corimu River Fracture Belt). One of the most serious areas of disasters, this strong earthquake will exacerbate the risk of geological disasters in the region.

In this regard, he reminded him that he should pay attention to preventing high remote geological disasters. "There are so many mountains in the local area, and the earthquake can easily cause a cracking mountain on the top of the mountain, or form a landslide accumulation that has not been rolled down for the time being. In the future, they may be transformed into high debris and mudslides due to rainfall, which in turn forms remote range Disaster chain. "

To do a good job of prevention, you must check the hidden danger points. But how can we discover hidden dangers faster and more accurate?

Speaking of this, Yin Yueping remembered the scene of the "May 12" Wenchuan Earthquake mainly relying on human resources to conduct ground investigation. "Although repeated inspections, investigations, and re -investigation, they have not fully grasped the characteristics of high -level remote geological disasters, resulting in leading to the characteristics of high -level geological disasters, resulting in leading to the characteristics of high -level geological disasters, resulting in leading to the characteristics of high -level geological disasters. There are many major disasters and dangers. "Compared with the time, satellite remote sensing, drones and ground surveying and mapping techniques have been more fast and efficient. Therefore, Yin Yueping believes that this time it should improve the accuracy of the survey of emergency high disaster sources. He said that related technologies have matured today, Sichuan Province is at the forefront of the country in this regard, and it is fully powerful and should be accurately discovered by the source of risk.

Combined with this specific situation, Yin Yinping specially suggested that Sichuan accelerate the promotion of technologies for investigation and use of drones. On the one hand, because many places in the earthquake -stricken areas have recently been more clouds and fogs, the timely acquisition of satellite remote sensing images has been delayed; on the other hand, most of the local high hidden dangers are distributed on the mountains of hundreds of meters, or even a kilometer of high mountains. The source of high disasters has congenital advantages. "A drone can be equivalent to the work efficiency of dozens of people. It can find out the boundary and volume of the high -level property, and help analyze the risk of remote disaster." He said this time this time he said that this time this time Earthquake emergency surveys can accelerate the pace of promotion in this regard. In areas that may threaten the lives of people in the disaster area, they will use drones to investigate hidden dangers as soon as possible. After the vegetation grows out, it will be difficult to check it. "

It is necessary to do a better survey of high -level disasters.

It is recommended to survey "slope to the top, the ditch to the end" on site in key areas.

Yin Yueping said that the emergency stage focuses on "discovering hidden dangers-to avoid", and the above methods can play a role; when the reconstruction stage must be considered, "comprehensive governance-scientific disaster prevention" is required, and a precise survey of high-level disaster matter needs to be further done. And carry out risk assessment of remote geological disaster dynamics.

Doing these two things is to avoid the "Domino brand effect" formed by high -level remote geological disasters caused huge losses. "Although the slippery body when the mountain began to roll off is very small, during the exercise The loose accumulation body, so the volume of the disaster will become large. According to the experience of the "5. 12 'Wenchuan Earthquake and the strong earthquake of Lushan, the disaster volume may increase by 10 or even 100 times; At the same time, they may slip far, and sometimes they can go to a few kilometers away, bringing major harm to the downstream reconstruction zone after the disaster. "

If there is no precise estimate about this, the consequences will be serious. Yin Yueping has seen more than one place in China, because of insufficient estimation of the property and insufficient research on dynamics, causing problems in the prevention and control of geological disasters. Due to the insufficient accuracy of geological survey in the early stage, and the unclear understanding of the dynamic process, it will lead to the later period. Disaster prevention projects fail. "For example, if the volume of the risk of sliding risk of the back edge is 1 million cubic meters, but the actual remote exercise reaches 10 million cubic meters, how can the prevention and control project be blocked?"

This is more important than blind pursuit. "Even if it can quickly complete the emergency investigation of post -earthquake geological disasters and make preventive plans, due to the insufficient accuracy of the early investigation and investigation and the lack of remote dynamic assessment methods, it will cause the rework of prevention and control projects, or even fail. It should be from the previous lessons. Detabage to experience. "

He also specially suggested that for the direct threat to major residents, the high -level remote geological disaster survey of the village and towns cannot just rely on technical means such as drones. Some things are hidden. To "the slope to the top, the ditch is going to the end". Of course, this requires professional field geological method training and technical guarantee.

It is necessary to conduct more professional monitoring and early warning

It is recommended to strengthen high -level remote mudslides professional monitoring and early warning, strengthen the application of visual equipment

During the interview, Yin Yueping specifically mentioned the "secondary disaster" caused by the earthquake, which did not mean that it was just a recent thing. "The name of the secondary disaster is easy to make people feel that they were accompanied by the earthquake. They thought that the earthquake ended, and they soon ended -but actually geological disasters may last for several years, even more than ten years." He thought he wanted to This reminds: Because the disaster duration lasts for a long time, we must pay attention to monitoring and early warning.

Regarding this aspect, Yin Yueping said that Sichuan has a lot of successful practice and experience, including group testing group defense, early risk aversion and other ideas and means that it has been proven to be effective. On this basis, he suggested that Sichuan strengthen the professional monitoring and early warning of high -level long -range mudslides.

He further stated that the "professional" here is to monitor and early warning of rainfall. "We usually say that the mountainous areas 'ten miles are different'. You may judge that it will not rain in the ditch in the ravine, but the Houshan has already rained a lot of rain. And the rainfall is an important trigger factor for mudslides, so it is necessary to do professional rainfall monitoring and early warning. "On the other hand, it is necessary to increase visual monitoring methods. Yin Yueping specifically mentioned that there are some new methods in monitoring mudslides, but they have to be tested. "Some equipment in the canyon area is easy to damage and the early warning is very difficult. Therefore, the application of visual equipment should be strengthened. Intelligent recognition can win the warning time for dozens of seconds or even a few minutes to the downstream. "
