本文可认为是发展一种普遍能应用的,由于粘滞流动引起沥青层永久变形的计算方法的尝试。应用以线弹性多层理论为根据的计算机程序,能够计算轮载作用下道路中的应力应变分布。将静应力应变分布变换成相对于速度V=x/t的“动分布”。因而,在每个给定点处的应力和应变就成为时间的函数。 This article may be considered as an attempt to develop a commonly applicable method of calculating the permanent deformation of bitumen layers due to viscous flow. Applying a computer program based on the linear elastic multilayer theory, the stress-strain distribution in a road under wheel load can be calculated. The static stress-strain distribution is transformed into a “dynamic distribution” with respect to velocity V = x / t. Thus, the stress and strain at each given point become a function of time.
