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方向位移在安全系数降低至1时均表现出下降趋势。
In order to study the relationship between the displacement of slope foot and the safety factor of slope stability, the finite element model of slope was established by using ABAQUS finite element analysis software. Combined with the shear strength reduction method, the corresponding edge Slope stability and safety factor, and in the slope foot range select 3 points for displacement observation. The observation results show that the displacements in all three directions increase nonlinearly with the decrease of safety factor, and the displacement of each point in X direction is larger than that in Y direction. When the safety factor is reduced to 1 When all showed a downward trend.
