简化Bishop法和有限元法在某矿区基坑边坡稳定分析中的应用

Application of Simplified Bishop Method and Finite Element Method in Slope Stabilization Analysis of a Foundation Ditch

以某矿区新建办公楼基坑边坡为例,采用极限平衡法中简化Bishop法以及有限元法进行计算分析,得到了边坡在自重作用下的安全系数以及水平位移等值云图、潜在滑面形状,说明了该边坡具有足够的安全储备,相对形象地给出了边坡的变形破坏机制,供设计、施工人员借鉴参考,以便及早发现隐患,采取措施。

Taking for example a foundation ditch slope of a newly-buih office building in a mining area, calculation was conducted by using simplified Bishop method and finite element method, gaining safety factor of slope under gravity and equivalent map of horizontal displacement and potential sliding face shape. It indicated that this slope had enough safety factors and gave relatively imaginarily deformation damage mechanism. It gave a reference to designers and constructors so as to fine hidden troubles and adopt measures.
