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.
