| 摘 要： | 为了研究长沙地铁袁家岭车站基坑对其周边建筑(电信公司2号楼)的影响,采用ABAQUS软件建立了三维有限元模型,土体考虑摩尔-库仑弹塑性和渗透性,周边建筑按总荷载被等效转换为地表压强,围护结构水平支撑被转换为等效压强或位移,模拟土体应力释放和降水渗流作用。此外,还模拟了补水回灌过程和潜水面下降对地表沉降的影响。在此基础上,本文预测并评估了周边建筑地基的沉降量和影响范围,提出了相应的建筑沉降控制标准,为长沙地铁的安全施工提供了参考。

| Abstract: | By the software ABAQUS,three-dimensional finite element models of the foundation pit of Yuanjialing underground station are created in this paper,in which the elastic-plasticity and seepage function of soils are considered to simulate the excavating process.On that basis,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 2nd line of Changsha Subway. |
