The dynamic analysis of pore pressure response in the saturated local inhomogeneous soil as solid grain being incompressible

CAO Huafeng,WEI Changfu (State Key Laboratory of Geomechanics and Geotechnical Engineering,Institute of Rock and Soil Mechanics, Chinese Academy of Sciences,Wuhan 430071,China)  
For analyzing the influence of the micro-mesoscopic inhomogeneous structures on the macroscopic mechanical property,based on the latest wave motion theory about the local inhomogeneous soil,the dynamic model of which could describe the influence of the local structure on the pore pressure dynamic response as the solid grain is incompressible.By using this model,the analytical solution of the pore pressure is achieved in the one-dimensional saturated soil layer bearing periodic load.Treating the relaxation time and the load frequency as variables,the influence trends of which in the pore pressure are analysed quantitatively,and the sensitive range of them are determined.
