摘　　要：利用复变函数法,给出了稳态SH波作用下浅埋多个弹性夹杂附近半圆形凸起地形地表位移的求解方程,在求解区域内分别构造满足各自边界条件的波函数,通过满足弹性夹杂的边界条件得到问题的定解方程组,基于求解方程组,可以得到凸起地形表面的位移场和浅埋夹杂的应力场变化情况。The solving equation was given by the complex variable function,which can be used to study the surface motion of a semi-cylindrical hill above multiple elastic inclusions under incident SH-waves. The different wave functions were constructed to satisfy the respective boundary conditions. And the infinite algebraic equations were established according to the boundary conditions of every elastic inclusion. The numerical results of the algebraic equations can be used to describe the variation of displacement field and stress field.
