【摘要】 本文给出了满足全部自由面边界条件的半无限弹性空间域内点加振的Ｇｒｅｅｎ函数，利用变形的Ｈａｎｋｅｌ函数，在复数域内进行无限积分的有限化，从而使Ｇｒｅｅｎ函数的计算变得比较简单和方便。更多还原

【Abstract】 A solution of Green’s function is presented for a point dynamic load in theinterior of an elastic half-space which fully satisfies the boundary conditions on the freesurface. By means of the modified Hankel functions,the infinite integral is transformed intofinite ones in the complex domain, which makes the evaluation of Green’s function easierand more conveniently This solution serves the theorectical basis for the application ofboundary element method in the analysis of dynamic soil-structure interaction problems。更多还原
