【摘要】 本文采用ABAQUS软件,对长沙市地铁袁家岭车站基坑建立三维有限元模型,考虑土体弹塑性和降水渗流作用来模拟开挖,预测了周边建筑地基的沉降变形,并提出了相应的建筑沉降控制标准,为长沙地铁二号线的安全施工提供了参考。更多还原

【Abstract】 In this paper,three-dimensional finite element models are created for the foundation pit of Yuanjialing underground station by the softwave ABAQUS,in which the elastic-plasticity and seepage function of soils are considered to simulate the excavating process.The settlement and deformation of the nearby building foundation are forecasted and the control criterion of building subsidence is advanced in the paper,to provide direction for the construction safety of the 2^nd line of Changsha Subway.更多还原
