| 摘 要： | 一、研究的目的和内容重视宏观的和微观的地质因素的岩体力学试验研究,有助于较真实地解释和确定岩块和岩体的变形、破坏的机理和力学的宏观现象,可以为选择和建立它们的破坏准则和强度理论,进行地壳岩体和工程岩体的稳定性分析评价等提供有用资料. 岩体是由宏观的结构面和结构体所构成,是地质体的一部分.岩体中包含着岩块.岩块和岩体的建造和改造决定了它们的物质组成和结构构造.

| Abstract: | In the paper ,the experimental results of some uniaxial compression tests preformed on samples of one kind of sandstone are deseribed .The sandstone tested is discontinuous and anisotropic .It contains a large amount of tensile fission which occur along a preexisted shear fracturing zone of geological structure in the rock mass .it is suggested in this paper that the deformation and failure of this kind of rock could be divided into five stages ,and the experimental results obtained could further be used to interpret the deformation and failure of rock masses . |
