A study on hemispherical canyon SH wave dispersion 半球形峡谷对SH波散射问题的初步研究
At first, the displacement field of the semi-cylindrical hill including a semi-cylindrical canyon under SH wave is provided. Then the scattering of SH wave by a semi-cylindrical hill adjoins a semi-cylindrical alluvial valley is solved based on the idea of domain division. 首先给出在半圆形凹陷的影响下,半圆形凸起地形对SH波散射的位移场;在此基础上,又求解了半圆形凸起地形在半圆形沉积层影响下对SH波的散射。
It is concluded that evident effects of differen width depth patios and shapes of canyon on SH wave scattering could be observed, and the influence of round amplification due to frequency are more significant. 结果表明:峡谷的宽深比a/b及其断面的形状对SH波的散射有明显的影响。而且频率的变化对地面放大作用影响显著。
