摘　　要：结合镇江迎江大厦基坑支护项目,讨论了在场地狭窄且有临近建筑物的情况下,进行基坑支护和开挖时所面临的问题,并采用有限元软件MIDAS进行三维有限元模拟,计算了基坑以及支护结构的受力和变形特征,通过与现场实测结果的对比分析,表明利用MIDAS进行环梁支撑基坑支护模拟是可行的,值得在工程中推广应用。Through Zhenjiang Whampoa properties Yingjiang building foundation pit supporting project,discussed the near field is narrow and there are adjacent buildings,foundation pit supporting and the problems facing when excavating. The three-dimensional finite element simulation by finite element software MIDAS,calculate the stress and deformation of retaining structure and foundation pit. Through the contrast analysis with the measured results,show that the use of MIDAS for ring beam supporting of foundation pit supporting simulation of feasibility,worthy of popularization and application in engineering.
