土石坝边坡小概率失效计算方法
Calculation of small failure probability in slopes of earth dams
摘要
Abstract
A hybrid subset simulation approach based on the linked-list sifting method and Kriging surrogate model is proposed to overcome the drawback that it takes long time for the Monte-Carlo-based stochastic finite element method to calculate small failure probability in slopes of earth dams.First,the linked-list sifting method is adopted to calculate initial sample points that can be used for training the Kriging surrogate model.Next,the Kriging surrogate model is used to predict the response values of conditional sample points at different levels of subset simulation,which are used to determine the slope failure probability.Finally,a slope example of an earth dam is given to illustrate that the proposed approach costs less time than other approaches,which is more suitable to calculate small failure probability in slopes of earth dams.关键词
