| 摘 要： | 局部地形对地震动的影响是地震工程学研究的重要课题，文章应用“契合”与多极坐标的方法对由多个半圆形凸起构成的复杂地形及其附近的圆形孔洞对SH波的散射与地震动问题进行了研究．最后通过具体算例，讨论了半圆形凸起地形表面上的地震动、浅埋圆孔周边位移及动应力集中系数．结果表明：多个凸起与浅埋圆孔之间相互影响明显，应该引起重视。

| Abstract: | The influence of local landforms on ground motion is an important problem in aseismatic research. Because of this, the interaction between multiple semicylindrical hills and subsurface circular cavity with incident SH-wave was studied.A complex function, multi-polar coordinate method and conjunction were employed.Numerical examples and a relative discussion on ground motion and dynamic stress concentration factors (DSCF) are provided. It was found that the interaction between multiple semi-cylindrical hills and subsurface circular cavity is so apparent that it warrants great attention. |
