| 摘 要： | 我国水泥混凝土路面设计经历了3个发展阶段：经验法、力学一经验法和可靠度设计法。由于荷载、环境作用和结构设计参数的随机性和模糊性，它们都将影响路面结构的可靠度水平。为了更好地发展现有路面设计理论，系统地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。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系统分析，研究提出了路面模糊随机可靠度的设计公式，讨论了各个设计变量的变异性，并结合具体设计提出了详细的步骤和思路。

| Abstract: | The design of cement concrete pavement has experienced three phases such as empirical method, mechanistic-empirical method and reliability design method. The random and fuzzy quality in the load, environment and design parameters will affect the reliability of pavement structure. In order to develop design theory more reasonable, the current design specification code of cement concrete pavement is systematically analyzed and the definition of reliability of pavement structure discussed. On the basis of the fuzzy-random reliability, the design formula for the fuzzy-random reliability of pavement is established and the variability of various design variables is discussed. Last, the detailed design steps and the practical design process are put forward. |
