运用ANSYS有限元软件，采用D-P弹塑性模型，通过改变隧道与基坑边线的距离，对地铁隧道的竖向和水平位移进行三维数值模拟，得出结果：基坑与隧道的距离越远，隧道各点的竖向位移越小；隧道的横向位移并不单调地随隧道与基坑距离的增大而减小，而是存在一个临界值使隧道的横向位移达到最大值，这个临界值约为基坑深度。

Using ANSYS finite element software coupled with D-P elastoplastic model ,and by means of changing the tunnel and foundation pit edge distance ,vertical and horizontal displacement of metro tunnel is simulated with the result that the farther the distance between the foundation pit and tunnel , the smaller the vertical displacement of each point of the tunnel is ;And the lateral displacement of the tunnel is not simply reduced monotonously with the increase in the distance of tunnel and excavation , which however has a critical value of the lateral displacement of the tunnel reaching the maximum val-ue .T he critical value is about the depth of foundation pit .
