摘要
采用有限元方法对边坡开挖进行数值计算,得到开挖后边坡的变形情况,并通过抗剪强度折减技术对开挖后的边坡材料进行强度折减,得到边坡破坏时的临界滑面和安全系数。有限元方法的计算结果不但能评价边坡的稳定性,还可得到潜在的危险区域,对边坡开挖施工有一定指导意义。
The Finite Elements Method（FEM） is implored to simulate excavation of slope.The deformation of the excavated slope is computed.The factor of safety of the slope is solved by using shear strength reduction technique and the critical slip surface can be easily obtained through the max shear strain contours of the slope at failure.The FEM results are able to evaluate the slope stability and the dangerous zone of the excavated slope can be obtained,which is valuable for slope excavation.
