传统的沥青路面设计方法中的一些主要设计参数都是定值,事实上,大部分设计参数是随机变量.为了掌握路面使用性能的变化,引入路面结构使用性能可靠度的概念,运用统计与概率的方法,利用ANSYS可靠性分析工具--Probabilistic Design,分析结构参数的变异性并结合蒙特卡罗法,得出了可靠度的计算方便且有足够的精度,符合实际工程需要,也是确保道路整体使用性能的关键之一.

Some of the key parameters in traditional methods of asphalt pavement design are valued. In fact,most of the design parameters are random variable. In order to master changes of pavement performance,this paper introduces the concept of reliability in service performance. uses statistical and probable methods,makes use of ANSYS-Probabilistic Design in the reliability analysis to analyze the variability and the distribution probability of structural parameters and cornbines with Monte Carlo method, shows effectively that reliability of the calculation has enough accuracy to calculate conveniencly and is in Iine with the actual work required. also the key of ensuring service performance of the whole road.
