波从单相介质向两相饱和多孔介质入射耗能时在交界面上的反射与透射

THE REFLECTION AND TRANSMISSION OF PLANE WAVES ON AN INTERFACE BETWEEN SOLID AND LIQUID-FILLED POROUS SOLID WITH DISSIPATION OF ENERGY

在Ｂｉｏｔ两相饱和多孔介质动力学理论的基础上，根据地震波从单相介质向两相饱和多孔介质入射时交界面上的连续性条件，推导了考虑能量耗散情况下平面Ｐ波和ＳＶ波以任意角入射时在交界面上的反射和透射计算公式。

On the basis of Biot's dynamic theory for liquid-saturated porous solid,the formulue are deduced for reflecting coeffcients and transmitting coefficients on the interface between solid and liquid-saturated porous solid while P wave and SV wave are incident at different angles.The continuous conditions on the interface are used and dissipation of energy is considered when waves are propagating from the solid medium to the liquid-saturated porous solid medium.
