摘要
进行了盾构法施工对周边环境影响的三维有限元数值计算的研究分析。针对广州地铁4号线的地质条件,三维有限元数值计算结果给出了地表变形的定性解,同时根据对盾构施工变形规律认识的基础上,能够有效的分析和预测在盾构法隧道施工过程中对周边环境的影响范围,并采取一些措施控制因盾构开挖引起的地表沉降。
In this paper, three-dimension FEM （Finite Element Method） is applied to study the influence of the surrounding environments by shield-driven. Considering the characteristics of geology in No. 4 line of Guangzhou subway , the calculation resuits of three-dimensional FEM give a qualitative comprehension of ground deformation , and on the basic of the rule of ground deformation caused by shield tunnelling, it analyses and predicts the quantity of effects on surrounding enviroments by shield tunnelling. And use some countermeasures in order to control the surface settlement by shield-driven.
