摘要

开挖面支护应力的控制是土压平衡式盾构施工成功的关键。利用能够考虑大变形破坏的拉格朗日有限差分计算程序，对土压平衡式盾构在黏土地层施工中，因开挖面支护压力控制不当引起的开挖面的变形及破坏问题进行计算分析，探讨了开挖面变形及破坏模式，分析了开挖引起的周围土体应力释放问题，为黏土地层中盾构开挖面控制压力的确定提供参考。

Abstract

The face support pressure control is a key operation during earth pressure balanced shield excavation. Three-dimensional fast Lagrangian differential finite element method can calculate the large strain of material

which is used to simulate the influence of face support pressure to face movement and collapse. Deformation and collapse pattern is discussed

and the soil stress release is analyzed due to shield excavation. Some useful results from numerical simulation are given for controlling face support pressure.
