| Abstract: | In this paper the 3 Dimensional nodal equivalent volume and equivalent flow are put forward. The development and dissipation of porewater pressure in the seismal process have been researched, and normal stress, shear stress and cycle number are considered. By using these conceptions 3 Dimensional dynamic nonlinear finite element formula have been worked out. The results show that this liquefaction analysis is feasible and its compution is clear and quick, so it's of great value to engineering practice. |
