摘　　要：采用三维有限元模拟盾构推进的过程 ,是研究盾构施工中土层移动的最有效的手段。本文采用三维弹塑性有限元 ,在真实模拟施工情况的基础上 ,研究了新隧道从老隧道下面垂直穿过时 ,对老隧道的变形影响情况。研究表明 。Using the 3D elasto\|plastic FEM to simulate the whole process of shiel driven tuneling is the most effective way to investigate the ground movement during the tunnel construction.Based on the simulation of the actual constrution condition, the influence of the nearly constructed tunnel on the old tunnel located vertically on the new tunnel being studied. \[
