汶川县三关庙后山不稳定斜坡成因机制
|
摘要
对汶川三关庙后山不稳定斜坡的基本特征进行了详细描述,并根据其变形特征深入分析其成因机制。结果表明,该不稳定斜坡主要控制因素为地形地貌、地层岩性及地质构造,主要诱发因素为汶川地震。此不稳定斜坡仅为汶川地震诱发的新增灾害点之一。对该灾害点形成特征及主控因素的分析,为类似地质环境条件的地质灾害研究提供参考。
The basic features of the slope are elaborated and an in-depth analysis is made of its formation mechanism according to the deformation characteristics.Its main controlling factors are topography,lithology and geological structure and its main triggering factor is 5.12 Wenchuan earthquake in 2008.This unstable slope is one of the new disasters triggered by Wenchuan Earthquake.The study of the slope's formation characteristics and main controlling factors can shed light on the research of similar geological disasters in similar geological environment.
