摘　　要：通过对各向同性弹性体力学中拉甫位移函数重新修正,并利用Hankel积分变换理论,在变换域内得到了横观各向同性地基的通解,从而求得单层地基的应力和位移解,运用矩阵传递方法和Hankel积分反演变换推导了层状横观各向同性地基在轴对称荷载作用下的解析解,给出了数值计算结果.By revising the Love displacement function of isotropic elastic mechanics,the general solution of axisymmetric problem of transversely isotropic foundation based on Hankel integrate transform is obtained in another style.The solution of stress and strain of single layer foundation is available in the field of transformation.By means of transfer matrix and Hankel,the explicit solution of axisymmetric problem in multilayer system is derived and the numerical examples are presented.
