摘要
根据工程结构可靠度概念,在假设路面结构的强度(X)和应力(Y)均符合正态分布情况下,利用一次二阶矩模型对沥青路面结构强度抵抗外在荷载应力的概率水平暨安全性进行了评价。分析了不同可靠度系数和变异系数条件下沥青路面结构的可靠度水平。并通过对广深高速公路等实体工程沥青路面的结构安全性的计算分析,证明了将可靠度理论引入沥青路面典型结构设计中是合理可行的。可供沥青路面结构设计、路面质量控制与管理提供借鉴和参考。
Safety of asphalt pavement structure has been evaluated by using the one and two order method in accordance with reliability theory, when assumed that the distribution of structure strength and stress fit the normal distribution. And the level of asphalt pavement structure reliability under the conditions of different reliability parameter and coeffi- cient of variation has been obtained. In this way, asphalt pavement structure reliability of Guangzhou - Shenzhen Expre- ssway has been evaluated. It has also proved that it is reasonable and feasible to introduce reliability theory structure design. To some extent, it can provide insightful reference for asphalt pavement design as well as agement and control over asphalt pavement. m pavement quality management and control over asphalt pavement.
