DECOMPOSITION OF POTENTIAL FUNCTIONS FOR DYNAMIC SOLID-FLUID COUPLING EQUATIONS OF LIQUID-SATURATED SOILS
饱和土介质的固-流耦合动力方程的势函数分解

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.
