摘　　要：通过对半无限弹性体的通解进行Hankel数值逆变换，得到两层地基内部受有轴对称荷载下的位移和应力解，通过改变参数进行了大量的数值计算，计算结果表明与文献中的研究结果一致，可用于设立于层状地基的桩基沉降计算。The displacement and stress solutions of two-layered soil under an axis-symmetric load can be obtained by making reverse Hankel transformation on the general solution to semi-infinite elastic mass .A numerical way of getting the displacement and stress is presented and a number of results are derived and compared with previous results, which is proved to be an efficient and accurate procedure. These results are very helpful to the future research work ,such as the computation and analysis of pile seeelement .
