交通部公路规划设计院主编的《公路柔性路面设计规范》,已经交通部批准,于1987年1月1日起实施。为配合上述规范的需要,广西交通科研所、哈尔滨建筑工程学院城建系、同济大学道路与交通工程研究所于1982年开始编制公路柔性路面计算机辅助设计程序。据悉,国内外已有些多层弹性体系的应力与位移计算程序,我们过去也在这方面进行过大量的工作,但这些程序都只能用于计算给定路面的应力与弯沉,而不能直接用于计算路面的厚度。要解决厚度计算,就面临着一个算法的问题。所采用的计算方法,必须既能满足计
Ministry of Transportation Road Planning and Design Institute editor of “Highway Flexible Pavement Design Code”, Ministry of Transportation has been approved by the January 1, 1987 come into operation. In order to meet the above specifications, Guangxi Traffic Research Institute, Harbin Institute of Urban Construction Department of Urban Construction, Tongji University Road and Traffic Engineering Institute in 1982 began compiling highway flexible pavement computer-aided design process. It is reported that there have been some programs of stress and displacement calculation for multi-layer elastic systems at home and abroad. In the past, we have done a lot of work in this field. However, these procedures can only be used to calculate the stress and deflection of a given road surface, not directly Used to calculate the thickness of the road surface. To solve the thickness calculation, it faces an algorithm problem. The calculation method used must be both met
