丹江口市库区移民集中安置点高切坡变形破坏模式研究

Study of Deformation and Failure Mode of High Cutting Slope in Resettlement Points of Danjiangkou Reservoir Area

通过开展丹江口市地质灾害详细调查,对丹江口市库区移民安置点高切坡空间分布、地质结构、变形破坏历史、防治情况等进行了调查,将其划分为土质高切坡、岩质高切坡、岩土质高切坡三种类型,在深入分析高切坡地质结构与变形破坏模式基础上,总结归纳出区内高切坡存在土体滑移型、顺层滑移型、切层滑移型、块状崩滑型等四种典型变形破坏模式,对于高切坡工程防治具有重要指导意义。

By conducting a detailed investigation of the geological disasters of Danjiangkou City, spatial distribution of high cutting slope, geological structure and deformation failure history and so on in resettlement points are investigated. It is divided into three kinds： soil high cutting slope, rock high cutting slope and rock soil high cutting slope. Based on in-depth analysis of geological structure and deformation failure mode, the paper summarizes four typical modes of deformation and failure, which has an important guiding significance for prevention of high cutting slope engineering.
