沥青路面结构的可靠度优化设计

Optimization Design of Reliability of Asphalt Pavement Structure

本文以交通部１９８７年施行的《公路柔性路面设计规范》（ＪＴＪｏ１４－８６）为基础，首先介绍了沥青路面可靠度设计的有关概念和方法，根据室内外大量实测资料提出了设计和施工参数的统计分析结果。然后，以设计可靠指标为约束条件，费用为目标函数，运用改进的网格优化算法，提出了沥青路面结构的可靠度优化设计方法，并编制了“沥青路面辅助设计系统”。

Based on 'Design Code of Highway Flexible Pavement'(JTJ014-86), the relevant concepts and methods of the reliability design of asphalt pavement are introduced, the analysized statistical results of the design and construction parameters are given according to a great deal of information obtained from indoor and outdoor tests. The method of the optimization design of the reliability of asphalt pavement structure is put forward with the reliability index of the design as the constraint condition, the cost as the target function and using the advanced bisection network optimization method. The 'System of the Assistant Design of Asphalt Pavement' is drawn up.
