| 摘 要： | 本文利用Ｌａｐｌａｃｅ变换和波函数展开方法讨论了在阶跃的ＳＨ位移波作用下半圆形凹陷地形的瞬态反应问题。经Ｌａｐｌａｃｅ反演后，求出了阶跃ＳＨ波通过凹陷地形后散射位移场的长期解。最后给出了在不同时刻凹陷地形表面上各点的位移反应。

| Abstract: | The problem of transient response of a semi-cylindrical canyon by a step displacement SH-wave in time is considered by means of Laplace transform and the method of expansion of Wave functions. Through the inversion of Laplace transform the long time solution of the scattering displacement field of the canyon after the step SH-Waves crossed over the canyon is obtained. Finally the displacement response of the points on the surface of the canyon is given for the different instant. |
