摘要
根据武汉市某深基坑支护工程,利用Midas/GTS建立三维数值分析模型,对不同的施工工况下基坑周围土体变形规律及对临近地铁隧道结构的影响进行了分析。模拟数据与实测数据基本吻合,验证了迈达斯在基坑桩撑支护数值分析方面的适用性和准确性;数据表明:基坑开挖的深度与基坑围护结构的水平位移存在正相关的函数关系。基坑开挖会对临近地隧道结构造成一定程度的水平侧向位移和竖向位移。
According to the supporting project of a deep foundation pit in Wuhan, a three-dimensional numerical analysis model is established by using Midas/GTS to analyze the deformation law of the soil around the excavation and the influence on the structure of the adjacent subway tunnel under different construction conditions. The simulation data is in agreement with the measured data, and the applicability and accuracy of Midas in the numerical analysis of foundation pit pile support are verified. The data show-s that the depth of foundation pit excavation and the horizontal displacement of the retaining structure of foundation pit have linear function relation. The excavation of the foundation pit will cause a certain lev- el lateral displacement and vertical displacement to the adjacent tunnel structure.
