Shear Instability of Saturated Soil Considering the Gradients of Strain and Pore Pressure

摘要

The dynamic instability of saturated soil considering the gradients of strain and pore pressure was discussed in this paper.The inertia and the drainage effects were considered and the Perturbation method was used. It is shown that the strain gradient and pore pressure gradient are positive factors for the instability of saturated soil.
