柔性路面设计的可靠性分析

The Reliability Analysis of Flexible Pavement Design

本文以交通部1986年颁布的公路柔性路面设计规范(JTJ014—86)为基础,提出了多指标的柔性路面可靠度分析方法。对设计指标和主要设计参数进行了概率统计和模拟分析,初步得出了它们的概率分布规律。另外,通过用不同的参数均值和变异系数进行了路面结构可靠度计算和敏感性分析。对可靠度分析方法在施工控制和质量检测等方面的应用进行了简略的讨论。

This paper presents a reliability analysis method of muiti-indexes for flexible pavement based on the current Highway Pavement Design Specification(JTJ014-86).The parametric analysis and probablistic analysis are carred out on the design indexes and principal parameterゎ,and probablistic distribu- tion laws of them are obtained.Furthermore,by varying the mean values of parameters and coefficient of variation,the reliability of road pavement is calculated and its sensitivity is also analyzed.Finally,the application of the reliability design methed to construction control and quality check are discussed briefly.
