摘　　要：从横观各向同性弹性体轴对称问题的基本方程出发,通过对各向同性下的Love位移函数重新修正,采用位移解法,同时利用Hankel积分变换和Bessel函数理论.得到了材料特征值s1=s2时,圆面积上作用均布垂直荷载的横观各向同性地基位移与应力分量的解析解.A general three-dimensional analysis for transversely isotropic axial symmetrical foundation in the image domain is derived strictly by the displacement function method and the Love＇s displacement function is modified, displacement function method is employed, at the same time Hankel integration transform and bessel function theory are employed in the solution. The solution of displacement and stress for uniformly distributed vertical load on circular area of transversely isotropic foundation is obtained under the condition that the characteristic root is equal.
