摘要

利用非连续变形分析岩石断裂方法（Discontinue Deformation Analysis for Rock Failure

DDARF）数值模拟技术对平行节理岩体试件进行理论分析和数值模拟

研究了不同侧压力状态和原生裂隙角度等物理参数对剪切破坏和峰值强度的影响程度

指出侧压力和裂隙角度是岩体发生剪切破坏的主要原因。依据实际地下工程情形

建立具有平行节理岩体的地下洞室模型

并利用非连续变形分析方法（Discontinue Deformation Analysis

DDA）模拟地下洞室开挖过程围岩结构位移和稳定性分析

研究结果表明

平行节理岩体在不同地应力条件和裂隙角度下对洞室周围岩体稳定性具有不同程度的影响。

Abstract

DDARF numerical simulation technique was used for theoretical analysis and numerical simulation of specimens of rock mass with parallel joints.The degree of influence of physical parameters

such as different pressure states and original crack angle on shear failure was researched.It is pointed out that the lateral pressure and crack angle are the primary reasons for shear faiture of rock mass.Analysis of surrounding rock structure for excavation of underground cavern in rock mass with two sets of parallel joints shows that under different terrestrial stress conditions

the influence of parallel joint of rock mass on stability of rock mass surrounding cavern is on the different levels.
