摘要
"五·一二"汶川大地震诱发多处地质灾害。该边坡形成地质灾害的主要诱因是"五·一二"大地震,该滑坡在地震作用下,两侧山脊产生两种不同的灾害类型:一种是高位滑坡,另一种是崩塌。在分析两种地质灾害的地质特征、变形特征的基础上,对两种地质灾害的成因机制进行了较深入地分析。通过对两种地质灾害成因机制的分析,进一步阐述了形成两种不同破坏模式的因素。
The Wenchuan earthquake unleash a host of geological disasters. The main case of the geological disasters of this slope are the same. Under seismic action, two different damage models appear on both sides of the ridge ： high landslide and collapse. This paper analyzes the formation mechanism of these two geological disasters, basing on geological characteristics and deformation characteristics. Through the analysis of the deformation characteristics, further expounds the factors of two differ- ent geological disaster modes.
