摘　　要：对轴对称弹性力学方程进行Ｈａｎｋｅｌ变换，并利用传递矩阵方法得出层状地基在内部轴对称荷载作用下的位移解。利用此解析解建立了求解层状地基中单桩沉降的计算方法，并与Ｐｏｕｌｏｓ，Ｒａｎｄｏｌｐｈ和Ｗｒｏｔｈ，Ｒａｊａｐａｋｓｅ等人的经典解答进行了比较。Solutions for displacements due to load in the interior of a layered soil are derived by solving the governing equations for axisymmetric elastic medium through Hankel transforms and the propagator matrices method. A numerical procedure is presented for the settlement analysis of single pile in a layered soil by applying the solution obtained. Extensive comparison has been made with the classical solutions of Poulos, Randolph and Wroth, Rajapakse. The figures and tables which are useful to the engineering practices are given at the end of the paper.
