摘要

引入一种基于滑移线上非线性本构关系的圆形洞室计算模型，并从这个模型推导得出洞室开挖后应力状态的非连续表达式。在该表达式中围岩的应力分区以及其中的应力值由一个不定的荷载参数控制。通过引入边界条件的方法确定荷载参数，解决了荷载参数不确定的问题。从围岩的应力分布状态确定荷载参数的取值范围，并计算得到不同荷载参数范围内围岩应力分布曲线。将围岩应力状态的解析解与局部剪切应变二维有限元程序的数值解进行比较验证，一致性较好。

Abstract

A computation model of circular openings based on nonlinear constitutive relationship along slip lines is introduced. Discontinuous expressions for stress state around the openings after excavation are deduced based on the model. Distributions and values of stresses in surrounding rock are controlled by a uncertain load parameter

which could be determined by introducing a boundary condition. Stress distribution curves of surrounding rock in different ranges of the load parameter are obtained

where the ranges of the load parameter are determined by stress state in surrounding rock. The discontinuous analytical solutions of surrounding rock stress state are consistent with the numerical solutions of two dimensional finite element code for local shear strain.
