用Fourier变换求半平面不连续位移的基本解

Finding Displacement Discontinuity Foundmental Solution in a Half- plane with Fourier Transform

利用Ａｉｒｙ应力函数和Ｄｉｒａｃｄｅｌｔａ广义函数，采用Ｆｏｒｉｅｒ变换的方法导出了全平面和半平面集中不连续位移的基本解．由于利用了积分变换表，本文的推导过程十分简单．

y making use of the Airy stress functi on and the Dirac delta function,this paper deduees the displacement discontinuity foundmen tal solution in a plane or half-plane with Fourier transformation.Since the integral transformtable is adopted,the process of deduction becomes very simple.
