摘要
进行边坡非线性有限元分析,探讨坡体变形的大小和分布状况,分析塑性区的扩展形态和滑动面的形成,从而确定合理的滑动面位置。根据确定的滑动面,采用极限平衡法计算边坡的安全系数,能够对边坡工程的稳定性进行评价。结合1个工程实例进行了分析说明。
A stability analysis method of nonlinear finite element method for slopes is established.The results of this method can provide a systematic description of the whole state,including deformation behaviors,extension of plastic zone,and formation and evolution of slip surface in slopes.After the location of the slip surface is determined,the limit equilibrium method is used to calculate the safety factors of slope and evaluate the slope stability.An example shows that this method established here is reasonable and effective.
