摘　　要： 传统的层状体系分析方法是由伯米斯特在1945年首先提出的,本文根据边界元法的特点,提出了用边界元法解决层状体系应力计算的方法。文章首先获得了核函数奇异积分的数学表达式,然后分析了无限单元的特性及其应用方法,最后通过分析比较得出边界元法与雪弗隆程序结果相近。这说明层状体系可用边界元方法来计算应力、应变及位移,这为求解层状体系提供了一种新的方法。 The theory of multi-layered elastic system was presented by Burmister in 1945. In this paper, the characteristics of boundary element method is analyzed. Based on Stokes's law, the mathematical expressions of singularity integrity of kernel function is obtained and the infinite boundary element is used to analyze infinite boundary conditions. The results show that the accuracy computed by BEMLAY program which is developed by the auther is better than Chevron's program which is based on multi-layered theory. A new method to analyze multi-layered system is presented.
