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 ,研究了盾构推进力的变化对地面变形的影响。
Using the 3d elasto-plastic FEM to simulate the shield advance is the most effective method to investigate the ground movement during construction of tunnel.Based on simulating the actual construction process,this paper studied the influence of shield force change on the deformation of ground surface.
