摘要: 通过有限弹性层状体系理论, 计算出大量的常用情况下的路面中层底面弯拉应力, 并利用回归分析的方法, 建立了弯拉应力与路面各结构层厚度与材料特性之间关系的回归方程, 可简便迅速地计算出中层底面弯拉应力.

关键词: 柔性路面, 弯拉应力, 弹性层状体系, 回归方程

Abstract: The stresses of flexible pavement surface are analyzed using multilayered media program. The data are taken as samples to regress a general formula which is expressed by basic function. In this way, engineers can get surface stress of pavement without depending on dignal computer and this formula is useful in backcalculation algorithm for falling weight deflection.

Key words: flexible pavement, bending stress, elastic multi-layer system, regression equation
