摘要
本文把强度折减理论用于有限元法中 ,成功地解决了有限元在边坡稳定分析中的应用问题。有限元法不但满足力的平衡条件 ,而且考虑了材料的应力应变关系 ,计算时不需做任何假定 ,使得计算结果更加精确合理 ,而且可以很直观的得到坡体的实际滑移面。本文结合工程算例 ,对边坡加锚杆前后的稳定性进行了分析 ,并与传统的求稳定系数的方法进行了比较 。
In this paper the strength reduction theory is applied in the FEM, which gives a solution to ap plication of FEM in analysis of slope stability. By applying the FEM, not only the requirements for force bat ance can be met, but the stress strain relationship is considered as well. The calculation results would be ac curate without taking any assumption and the actual sliding surface can be obtained. Based on the example in practice, the slope stability before and after bolting was analyzed and the results are compared with thos from the traditional method. It shows that FEM can be used for solving the slope analysis problems.
