汶川地震地质灾害调查成果与展望

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。

Research Achievements and Prospects on Wenchuan Earthquake-induced Geohazard Investigation

The Wenchuan earthquake on May 12, 2008 is the most destructive large magnitude earthquake inducing the worst geohazards after the founding of new China. The main research achievements and results of the project entitled "Investigation and Evaluation of the Wenchuan Earthquake-induced Geohazards" are presented in this paper. By using technologies such as whole space-aerial-ground investigation, geophysical detection, GPS displacement monitoring, slope ground motion testing, and large physical simulation, the development features of the Wenchuan earthquake-induced geohazards were investigated, and the forming mechanisms of the geohazards caused by coupling endogenic and exogenic geological processes were preliminarily revealed. In order to meet the needs of reconstruction of the earthquake region, a series of key technologies for high-position debris flow prevention and monitoring and early warning were used to provide technical support for major geohazard monitoring and warning, as well as post-disaster reconstruction, in susceptive strong earthquake mountainous regions.
