摘要

本文提出了考虑底部弱弹性的共振相互作用模态的模态抛物方程方法。对该方法进行了数值验证。对ASA楔形基准进行的测试计算证明，对于海底软沉积物典型的剪切波速足够小的值，与源图像方法非常吻合。

Examples of test calculations by the acoustic mode parabolic equation with the mode interaction and the elastic bottom

In this work a mode parabolic equation method for resonantly interacting modes accounting for the weak elasticity in the bottom is developed. The proposed method is tested numerically. The test calculations carried out for the ASA wedge benchmark prove an excellent agreement with the source images method for sufficiently small values of shear waves speed that are typical for soft sediments of the sea bottom.
