【摘要】 基于滑面正应力修正的极限平衡法是近年来发展起来的一种边坡稳定性分析方法,具有良好的发展潜力。在已有工作的基础上,对该方法的研究成果作了系统的归纳总结,主要包括基本理论的建立和完善、二维与三维极限平衡研究和典型工程应用等三大方面。同时介绍了借助该方法的基本原理在加固边坡的稳定性、三维边坡滑带强度参数的反演分析、地震作用下的三维边坡稳定性评价、三维边坡稳定性分析中的端部效应等方面取得的进展。最后,对该课题的研究不足和下阶段的研究方向进行了阐述。更多还原

【Abstract】 As a new type of slope stability analysis,the limit equilibrium method by modifying normal stresses over slip surface has a distinct advantage.The research results were analyzed and summarized in detail based on previous work,which were classified into three kinds: established and completed the basic theory,two-dimensional and three-dimensional limit equilibrium method,and some typical engineering applications.This paper also reviewed stability analysis of slope reinforced,3D back analysis on shear strength parameters of slip soil,stability analysis of 3D slope under earthquake action,and analysis of three-dimensional end effects of slopes,which based on the basic concept of the limit equilibrium method by modifying normal stresses over slip surface.Finally,some deficiencies in this study were discussed and suggestions were made for the further studies.更多还原
