摘要
为了更好地发展和完善现有水泥混凝土路面结构设计理论,系统分析了现有水泥混凝土路面设计规范,对路面结构可靠度进行了定义和讨论.考虑到行车荷载、环境作用和结构设计参数均具有随机性和模糊性,采用模糊随机可靠度理论,对水泥混凝土路面结构可靠度设计方法进行了详细的分析,提出了路面模糊随机可靠度的设计公式,讨论了水泥混凝土路面的疲劳寿命和路面标准轴载累计作用次数及各项设计参数的变异性,并结合具体设计提出了详细的步骤和思路.模糊随机可靠度设计方法为路面设计理论提供了一种新的分析思路,有助于进一步深入研究路面设计方法.
In order to develop the current pavement design theory more scientifically, this paper systematically analyzes the design specification code of cement concert pavement of China and discusses the definition of reliability of pavement structure. The fuzzy-random reliability theory is adopted by considering the random and fuzzy character of the vehicle loads, natural environment and design parameters. After a systematical analysis, the pavement design formula is established based on the fuzzy-random reliability. The variability of fatigue life N of cement concrete pavement and standard accumulative loads n including various design variables are discussed. Finally, the detailed design steps in the practical design process are put forward. The design method based on the fuzzy-random reliability provides a new research direction for the design theory of road, which is favorable to the further study of road design.
