【摘要】 为全面了解硬包体力学模型的基本力学性质，本文对软、硬匀质介质模型，非匀质软、硬包体模型及含有软弱层或空穴的不连续介质模型进行了三维弹性有限元分析。在常规围压作用下，得到了各具不同特征的位移场、应力场及变形势能密度场，对硬包体模型的发震条件、震源分布及前兆机理进行了探讨性研究更多还原

【Abstract】 Scientists over the world support hard inclusion proposed by Mei Shirong in eighties,but papers about its mechanics behavior are little.In this paper,soft,hard homogeneous model,soft,hard inhomogeneous inclusion,and model with weak layer or hole are analyzed by using 3-d linear elastic finite element method under conventional surrounding pressures.Variation of displaceements stress and corresponding strain energy field are obtained.The result and conclusions are valuable to study seismogenetic mechanism etc.更多还原
