摘要
盾构隧道开挖过程中周围土体应力重分布以及衬砌结构与土体相互作用,是盾构施工过程中地层扰动的内在原因,是有限元分析的关键因素,本文针对软土地区的特点,利用大型通用有限元软件ABAQUS对盾构隧道施工过程进行了有限元模拟。
The stress redistribution in soil and the soil-structure interaction in shield tunneling are the main cause of ground disturbance induced by tunnel construction,and they are also the key factor of finite element analysis.In this paper,author utilize the general finite element software ABAQUS to simulate the construction of shield tunneling,and a practical problem is analyzed to show the performance of the proposed numerical procedure.
