一、前言为了搞清地下岩体变形,破坏性态并得到岩体结构物的设计资料,人们一直对在岩体中采出的岩石试件进行各种强度试验。但我们认为,想通过这些强度试验来充分了解含有很多宏观和微观缺陷及空穴的岩石类脆性材料的破坏过程是十分困难的。自格里菲斯(Griffith)开始进行有关岩石破坏过程的
I. INTRODUCTION In order to understand the deformation and destructive behavior of underground rock masses and to obtain the design information of rock mass structures, various strength tests have been carried out on rock samples taken from the rock mass. However, in our opinion, it is very difficult to fully understand the destructive process of rock-like brittle materials containing many macroscopic and microscopic defects and holes through these intensity tests. Since Griffith began the process of rock destruction
