基于上限定理的边坡潜在破裂面确定方法与稳定性判识研究
Study of stability discriminant of slope and position determination of potential sliding surface based on upper bound theorem
摘要
Abstract
The stability discriminant of slopes and the position determination of potential sliding surfaces are always the research hot spots in geotechnical engineering. According to the upper bound method, and assuming the slope material obeys Mohr-Coulomn criterion, the internal and external works are calculated respectively by dividing slope body into blocks with regarding the potential sliding surface as a group of several sectional planes. Then the multivariate function to calculation critical height of slope is established and optimized by mathematical method, which is determined to the critical height and sliding surface shape. Through the example analysis and comparison with the previous research, the results show that the method in this paper is reasonable and effective, and can be used to determine the potential sliding surface and discriminate slope stability.关键词
