| Abstract: | In this paper, based on the simplified method of total stress for seismic liquefaction of building's subsoil and combined with nonlinear constitutive relationship of soils and Martin's model of pore water pressure, a simplified method is suggested for evaluating pore water pressure of building's nonlinear subsoil. The method could be applied to analyze liquefaction potential of subsoil of building, directly in terms of pore pressure ratio. |
| Keywords: | subsoil of buildings cone model nonlinear pore water pressure seismic liquefaction |
