| 摘 要： | 通过收集并分析大量国内外有关地震诱发地质灾害的文献资料,通过实地野外调查,结合汶川地震这一极端事件,展开对地震诱发地质灾害发育规律、分布特征及成因机理的研究,选取了2类共10个评价因子,包括:坡度、剖面形态、平面形态、高程、水系、岩组、岩体结构、断层性质、断层距离和斜坡方向,建立了一套针对地震条件下地质灾害易发性评价指标体系及方法.结合汶川县城研究区,进行了大比例尺评价尺度强震条件下崩滑灾害易发性评价,评价结果可为城镇建设及规划提供科学的依据,从而有效地规避风险和减灾防灾.

| Abstract: | By collecting and reading a lot of literatures of earthquake induced geohazard with fieldwork,a thoroughly study was carried on the mechanism,distribution and rule of seismic geohazard induced by WenChuan earthquake,a total of 10 factors in two categories were selected,and the factors consisted of terrain slope,profile type,plane type,altitude,river system,engineering geological rock groups,geologic structure,fault type,the distance from fault,and slope direction.The geohazard susceptibility index system an... |
