摘要
本文以丹江口库区许家畈安置点高切坡应急抢险工程为对象,分析了该高切坡的工程地质条件,阐述了其可能出现的失稳模式。选取3-3′剖面作为典型计算剖面,分别采用基于刚体极限平衡法(RLEM)的圆弧滑动法、折线滑动法和基于有限单元法(FEM)的强度折减法、赤平极射投影分析法对稳定性进行计算,对高切坡稳定性进行了评价,根据该高切坡的设计方案,基于RLEM与FEM,对治理后的边坡进行了稳定性分析与评价。
The geological conditions of the high cut slope emergency project are analyzed in the paper with high cut slope emergency project in Xujiafan settlement site of Danjiangkou Reservoir area as an example.The possible instability modes are expounded.3-3′profile is selected as a typical profile for calculation.The circular sliding method and the broken line slide method based on the rigid body limit equilibrium method(RLEM)as well as the strength subtraction method and plane projection method based on the finite element method(FEM)are respectively adopted for calculating the stability.The stability of the high cut slope stability is evaluated.The treated slope stability is analyzed and evaluated according to the design scheme of high cut slopes based on RLEM and FEM.
