摘　　要：针对流体与孔隙介质边界可能出现闭孔边界的情况,研究了从理想流体入射到黏滞流体饱和孔隙介质的弹性波反射问题,计算考察了采用顾及喷射流动动力学机制的BISQ模型下介质参数对反射系数的影响,并与开孔边界的情况和采用Biot模型的结果进行了对比。结果表明边界状况对采用BISQ模型的反射系数影响更明显。Reflection of inclined incident elastic waves at a fliud/fliud saturated poroelastic solid interface is studied. Attention is focused on the influence of the sealed-pore boundary on the reflection coefficient predicted by BISQ model. The results are also compared with those based on Biot theory. The study shows that the effect of boundary condition on the reflection coefficient is noticeable based on BISQ model.
