四川南充龙头山滑坡发育特征与形成演化
|
摘要
在龙头山滑坡基本发育特征详细调查的基础上,对滑坡的形成条件和演化过程进行了深入分析。滑坡的形成条件包括:(1)浅湖相和半深湖相的沉积建造是龙头山滑坡形成的物质条件;(2)斜坡多面临空的地形提供了良好的空间条件;(3)斜坡存在一组具有一定规模的NNW走向的陡倾导水横张节理系统是龙头山滑坡形成的结构条件,通过分析区域构造形迹和地表构造变形破裂认为,该组张节理是在NNW-SSE向历史构造挤压作用下形成的;(4)NNW走向的陡倾导水横张节理与暗红色泥岩顶面组成了斜坡内部垂直和水平的地下水渗透网络。滑坡的形成经历了成坡阶段、时效变形阶段和平推式滑移阶段。
The formation conditions and evolution process analysis of Longtoushan landslide was completed. The formation conditions includes:(1)shallow lacustrine facies and semi-deep lacustrine facies mudstone is the material condition;(2)slope face space provide good space conditions;(3)the existence of a series of steep slope water transverse open joints with certain NNW strike provides structure condition,based on structure features and traces analysis,it has been revealed that the open joints were strongly influenced by geological structures;(4)the steep open joints and the superface of semi-deep lacustrine facies mudstone composed the penetration networks. The landslide experienced slope forming stage,aging deformation stage and translational sliding stage.
