| 摘 要： | 为预测某大厦深基坑施工对邻近地铁隧道的影响,首先计算了该基坑近地铁侧围护结构在不同工况下的位移,得出其最大位移曲线;在此基础上,采用半经验、半理论的方法对地铁隧道处土体的水平位移和竖向位移进行计算,以此来保守估计地铁隧道的结构变形.

| Abstract: | To predict the influence induced by excavating the deep foundation pit on metro tunnel,the displacement of the retaining wall of the foundation pit must be firstly calculated in different constructing phases,and the curve of maximum displacement be figured out;then the vertical and horizontal displacements of the soil mass on the very place of metro tunnel shall be calculated by experiential and theoretical methods,only by doing so,the deformation of the metro tunnel structure can be moderately predicted. |
