| 摘 要： | 为研究坡脚位移与边坡稳定安全系数的关系,利用ABAQUS有限元分析软件,建立边坡有限元模型,结合抗剪强度折减法,在改变坡顶均布荷载的情况下分别计算相应的边坡稳定安全系数,并在坡脚范围内选取3个点进行位移观测.观测结果表明:3个观测点各方向的位移均随安全系数的减小而非线性地增大,各点X方向位移的变化幅度比Y方向大,各点Y...

| Abstract: | In order to research the relationship between displacements at the base of slope and safety factors,finite element model of a slope was built by ABAQUS finite element software.The corresponding safety factors were solved by combining strength reduction method with finite element as uniform load values in the top of the slope were varied,and three points were also selected on base area in order to record their displacements.The result shows that displacements of different points on base area increase nonline... |
