摘要
根据对陕西省留坝县因汶川"5.12"地震引发的地质灾害的调查和分析以及与地震前调查结果的对比分析,研究了"5.12"地震引发的地质灾害的特点。留坝县"5.12"地震引发的地质灾害主要为崩塌,根据崩塌体母体所在位置,可将其划分为山巅型和山腰型,两者崩塌母体所处的地形有明显差别,运动距离、方式及危害也有明显的不同。作者结合留坝县地震引发地质灾害的实际情况,得到关于地质灾害调查、评价和防治等方面的一些启示,对地质灾害的研究具有一定的借鉴意义。
According to site investigation and contrasting analysis on the geological hazards in Liuba county of Shaanxi prov ince triggered by the ＂5.12＂ Wenchuan earthquake. The characteristics of the hazards are studied. The main geological hazards are rockfalls which may be divided into mountain-slope type and mountain top type according to the position of their source of formation. They are quite different in the relief of origin, distance and mode of movement as well as the disasters. The lessons about the investigation, evaluation and prevention of geological hazards learned from the study are given, which is important for further research on the geological hazard.
