摘要
采用弹塑性二维非线性静力有限元法分析了某桥台岸坡的静力稳定性,然后将计算结果作为初始应力分析了该桥台岸坡在9度地震作用下的滑移稳定性,并通过三种台位和四种基础形式的对比分析,提出了合理的桥台位置、基础形式及应该采取的工程措施。
Based on the elasto-plastic,two-dimensional non-linear static finite element method,the static stability of an abutment slope is analyzed,and the computation result will be considered as the original stress. Then the stability of the abutment slope under earthquake is analyzed. By contrastive analysis of three positions of abutment and four kinds of base forms,the reasonable schemes about abutment positions,base form and project measures are put forward.
