摘要/Abstract

摘要：

对于具有复杂空间几何特征和地质构造的实际工程边坡,在进行稳定分析评价时,需对其进行三维分析。通过发展完善边坡稳定分析的三维极限平衡法程序CORE-lam3D,可模拟真实的坡面、地质界面、地下水位面、滑动面等复杂空间曲面,可采用3种三维极限平衡分析方法对潜在的滑动面及其可能多个滑动方向进行分析计算,可分析水荷载、地震荷载、加锚等因素作用的影响。通过对瀑布沟库首右岸拉裂变形体的稳定性进行研究,说明了CORE-lam3D的实用性和可靠性。

Abstract:

Three-dimensional method is needed in the stability analysis for slope projects with complex spatial geometric features and geological structures. A computer program CORE-lam3D for 3-D slope stability analysis was improved and developed. The program can simulate complex space surface such as real slope, geologic boundary, groundwater level and slip surface. Potential sliding surfaces and sliding directions can be calculated with three 3-D limit equilibrium analysis methods, and the impacts of water load, seismic load and anchoring forces were analyzed. The analysis results of a tension-distorted body on the right bank of the reservoir at Pubugou hydropower station verified the efficiency and applicability of the improved CORE-lam3D program.

Key words: slope stability analysis , 3-D limit equilibrium method , the most dangerous sliding direction , simulation of slope surface
