COUPLING ALGORITHM OF SIMULATED ANNEALING ALGORITHM AND RANDOM SEARCH METHOD FOR SLOPE STABILITY ANALYSIS
滑坡和边坡稳定性分析的模拟退火-随机搜索耦合算法

For the stability analysis of slope of non-circular slip surface,any partial optimization solution is possible to overvalue the safety factor. In this paper,a general optimization model applicable to optimization analysis of slope stability under any complex conditions,including complex boundary and shape of slope surface and soil data,is firstly presented,and then a coupling algorithm of simulated annealing algorithm and random search method is introduced for giving a global search method of slope stability analysis. Such a coupling algorithm combines the merits of the two methods. Three practical examples,with minimum safety factors and associated slip surfaces known,are carefully calculated and analyzed,and the feasibility and efficiency of the proposed coupling algorithm are proved.
