摘要
为分析地铁车站基坑开挖时支撑失效对地下连续墙的影响,结合浙大国际学院地铁车站进行监测和有限元模拟,并对地下连续墙支撑失效时对墙体变形、支撑轴力、地表沉降的影响进行了分析。结果表明:模拟结果与实际监测结果相符;支撑失效对基坑的危害性呈现从第四道支撑到第一道支撑递增的情况。
In order to analyze the influence of support failure on the underground continuous wall during excavation of the subway station foundation pit,the paper combines the monitoring analysis and numerical simulation analysis of the Zhejiang University International College subway station;the effects of wall continuous wall support failure on wall stress and deformation,support axial force and surface settlement are analyzed.The results show that the simulation results are consistent with the actual monitoring results;the hazard of support failure presents a situation from the fourth support to the first support increase.
