边坡稳定性分析的一个改建条分法

REBUILT SLICE METHOD FOR SLOPE STABILITY ANALYSIS

从塑性力学理论出发,提出了一个力图严格符合塑性力学极限分析原理同时又与现行条分法相衔接的改建条分法。将条分法归结为一个静力许可场中的大规模极值问题,然后应用改进的模拟退火算法求解,结果表明收敛性良好。与毕肖普法比较的结果显示了两种方法之间具有相当好的吻合性。

An attempt is made to present a rebuilt slice method, which is strict in conformity with the plastic limit analysis theory, and is simultaneously able to be related with the traditional slice-method. The slice method is reduced into a large-scale extremum problem in static permission field. The results of the extremum problem solved by the improved annealing simulation algorithm show that the convergence of solution is very good. The comparison with the Bishop method also shows good coincidence between these tow methods.
