| 摘 要： | 利用固相和流相位移势函数，把饱和土介质的固-流耦合矢量动力方程分解成为解耦的无旋波和等容波方程，从而使问题的求解大为简化。同时，讨论了土体的孔隙水可自由流动和无渗流的情况，得到了一些有意义的结论。

| Abstract: | By using potential functions of solid-phase and liquid-phase displacements, the dynamic solid-fluid coupling vector equations of liquid-saturated soil are decomposed into the decoupled equations of irrotational wave and isometric wave, so that the dynamic analysis is greatly simplified. Simultaneously, the cases in which porous water flows freely and does not seeps into soils are discussed and some very useful conclusions are obtained. |
