倾斜粘弹性覆盖层中P-SV波的广义射线法及物理模型实验

Generalized Ray Method and Physical Model Experiment for P-SV Waves in Dipping Viscoelastic Layer

本文用数值计算和超声物理模型实验两种方法研究倾斜粘弹性覆盖层中P-SV波的传播。理论方法是Pao,Ziegler和王贻荪的广义射线法的推广。文中导出了由第j次广义反射波产生的第(j+1)次广义反射波的一般形式。数值结果和物理模型实验结果是一致的。

Both numerical calculations and supersonic physical model experiments are used in the study of P-SV waves in dipping viscoelastic layer. The numerical method used here is the generalized ray method used by Pao, Ziegler and Wang. Formulas of (j+1)th generalized reflected waves caused by jth generalized reflected waves are obtained in general. The results of the numerical calculation and experiment are in good agreement.
