2008年5.12汶川地震是新中国成立以来破坏性最强、诱发地质灾害最严重的一次特大地震。本文简要介绍了国土资源地质大调查计划项目“汶川地震地质灾害调查评价”的主要研究进展与成果:采用空天地一体化调查、地球物理探测、GPS位移监测、斜坡地震动测试及大型物理模拟等技术,调查和研究了汶川地震地质灾害发育特征和分布规律,揭示内外动力耦合作用下的地质灾害成灾机理,并开展了震后重建区高位滑坡泥石流防治和监测预警关键技术研究,为强震山区重大地质灾害监测预警和灾后重建提供了技术支撑。
The 5.12 Wenchuan earthquake in 2008 was the most devastating earthquake ever since the founding of People’s Republic of China and the most serious geological disaster. This article briefly introduces the main research achievements and achievements of the project of Geological Hazards Investigation and Assessment of Wenchuan Earthquake, a large-scale land survey project of national geology and geology, adopting the integrated survey of air and space, geophysical exploration, GPS displacement monitoring, slope ground motion testing and large-scale physics Simulation and other techniques to investigate and study the development characteristics and distribution of geological disasters in Wenchuan earthquake, to reveal the mechanism of geological disasters under the coupling of internal and external dynamic forces, and to carry out the key technologies of prevention and control of high landslide debris flows and post-earthquake debris flow monitoring in post-earthquake reconstruction areas. Strong earthquake in major geological disaster monitoring and early warning and post-disaster reconstruction to provide technical support.
