摘要
本文介绍了在压缩荷载作用下,含一组未闭合断续节理石膏模型试验成果,结合试验中观察到的力学性状,运用断裂力学理论,着重分析了这类岩体的破坏机理及强度特性,并提出了估算该类岩体的两种强度准则。
This paper discusses the test results of a gypsum model with a group of open intermittent joints subjected to compressive loading. Combined with mechanical behavior observed during the experiment, the failure mechanism and the strength behavior of this kind of rock mass have been analysed mainly by means of fracture mechanics. Finally, two kinds of strength criteria for estimating this class of rock mass are proposed.
