岩爆发生的规律和断裂力学机理分析

Regularity of Rock Bursts andits Analysis Based on Fracture Mechanics

摘要: 本文由静力平衡、强度破坏和断裂破坏三者既联系、又区别，并共同作用于岩爆工作面的观点出发，通过对发生岩爆的掘进面上两种计算模型的断裂力学研究，确定出判明发生岩爆的力学机理和临界条件，从而对岩爆发生的总体规律作出了定量解释。

Abstract: From the Viewpoint of static epuilibrium,strength criterion and fracture criterion,two different models on the front face of the rock are used to establish the mechanical mechanism and critical condition of rock bursts and hence the regularity of rock bursts is explained quantitatively.
