中文摘要: 2008年5月12日14时28分,四川汶川发生里氏8.0级地震给灾区人民带来了巨大的灾难和损失,特别是山区地震次生地质灾害所带来的严重后果是人们始料未及的。本文主要报道了四川境内震中附近几个重灾山区的地震次生地质灾害的初步调查成果,简要论述了地震诱发的滑坡、崩塌、泥石流、地裂缝和沙土液化等次生地质灾害发育特征及其危害,提出了地震次生地质灾害某些发育规律方面一些认识和今后需要进一步研究的问题,对于灾后重建和高烈度区城镇规划具有一定的指导意义。

Abstract:An earthquake of MS8.0 hit Wenchuan, Sichuan, on May 12, 2008 at 2:28 p.m. Beijing time, which brought serious disasters and great loss of property to the people of the earthquakehit areas.Especially the serious consequence that the earthquake-induced geohazards in mountainous areas caused was unexpected.This paper mainly reports the primary investigation results of the earthquake-induced geohazards in some worst-hit mountainous areas near the epicenter in Sichuan, briefly describes the characteristics of development and harm of earthquake-induced geohazards such as lan dslide, rockfalls, debris flow, ground fissures and sand-soil liquation and presents some ideas about the development mechanisms of earthquake-induced geohazards and problems that need to be further studied.All these have certain significance for guiding the reconstruction of earthquake-hit areas and planning cities and towns in high-intensity areas.
