层状地基轴对称问题的Mindlin解

本文在文献1]的基础上,对层状地基应力和位移的计算方法做了一些创新的工作。首先作者提出求解传矩阵的逆矩阵的简便公式。并在应力、位移的计算上,对荷载作用面上下分别采用二种不同的传递矩阵。加快了计算速度,避免了层状体系计算中常见的溢出问题及大数减大数造成的计算困难。

The Mindlin's solution for axially symmetric problem of multilayer subsoils

In this paper,the authors obtain the Mindlin's solution of axially symmetric problems in a multilayer elastic system by Hankel transform technique and transfer matrix method. In order to avoid overflow in calculation, two different transfer matrices are used respectively for the two domains lower or higher than the load application plane to calculate the displacements and stresses.
