摘　　要：为研究地震时局部地形与附近浅埋结构的作用,文中使用"分区"思想,复变函数法和移动坐标的方法,建立多个浅埋圆形孔洞附近的多个含孔半圆形凸起地形对SH波的散射的数学模型,并通过算例给出含孔半圆形凸起地形的地表位移,讨论了浅埋圆孔的深度、含孔半圆形凸起间距及浅埋圆孔间距对地表位移影响。The authors studied the interaction between local terrain and subsurface structures during earthquakes. The idea of subarea, functions of complex variables and mobile coordinate method are used in the article. A model of the scattering of SH-waves by multiple semi-cylindrical hills with hole above subsurface multiple cavity is founded. Surface remove of semi-cylindrical hill-like protruding with a cavity is presented by examples. The influences of the distance of the two semi-cylindrical hills and the two subsurface circular cavities and the deepness of subsurface cavities on the surface remove are discussed.
