| Abstract: | The general methods for calculating initial pore water pressure in numerical analysis of saturated-unsaturated seepage flow are summarized herein. The distribution of pore water pressure generalized by the measured data and the initial pore water pressure calculated by adopting solutions of stable seepage flow are discussed, and then their own scopes of application and the related problems are described as well. Furthermore, the content of study for determining the initial condition of saturated-unsaturated and steady seepage flow field is presented at last. |
