摘　　要：本文运用边界元法解决路面应力分析问题,在多层路面应力分析中,引入了边界元分区组合子结构方法。计算结果表明,在路面应力分析中,边界元法具有数据准备简单,计算工作量少、速度快、精度高等优点。In this paper, the boundary element method (BEM) is applied for stress analysis of the flexible pavcment. The blocks-assembly method was introduced into calculating stress components of multiple layer pavement here. The computed results show that BEM have the advantage of simplified datum, less computer amount, rapid computing speed and high precision etc.
