延安市凤凰山东北麓滑坡危险斜坡的变形特征及稳定性分析

Analysis of deformation features and stability of landslides and hazardous slopes in the Northeast part of Fenghuang mountain in Yanan

通过对凤凰山东北麓工程地质特征的分析,指出该区存在的不良地质问题有滑坡(滑塌)以及危险斜坡等,并对各滑坡(滑塌)以及危险斜坡的变形破坏特征进行了分析,最后运用斜坡(滑坡)稳定性计算中常用的瑞典法、毕肖普法和剩余推力法对其进行了稳定性验算,为凤凰山东北麓后期的治理设计提供了依据。

By analyzing the features of engineering geology of Northeast part Fenghuang mountain in Yanan, the adverse geological problems including landslides,slumps,collapse and hazardous slopes are presented and their stability is assessed by virtue of Bishop's method and surphas thrust method commonly used in limit equilibrium analysis,in order to supply the reliable basis for future design schemes.
