【摘要】 通过采用岩样干燥、自然和饱和状态下的物理力学性能试验,对丹江口水库库区代表性岩样的软化性能进行了研究,以此探讨岩石软化作用,为丹江口水库续建工程诱发地震机理研究提供基础数据。结果表明,随着试件含水率的增加,岩石单轴抗压强度、弹性模量和泊松比均下降,岩石的软化系数与孔隙比有直接关系。更多还原

【Abstract】 By the physics-mechanics property examination of rock speimens which are on dry state,natural state and saturation state,Softening property of typical rocks are experimented in Danjiangkou Reservoir area;which can provide basic data for the study on reservoir-induced seismicity mechanism of the subsequent object of Danjiangkou Reservoir.The result shows that values of physical mechanics parameters reduce with the decrease of water ratio in rock,including uniaxial compressive strength,elastic modulus and Poisson’s ratio.So the softening coefficients of rocks are directly related to void ratios.更多还原
