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-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。
China’s cement concrete pavement design has experienced three stages of development: experience, mechanics - experience and reliability design. Due to the randomness and fuzziness of loads, environmental effects and structural design parameters, they all affect the reliability of the pavement structure. In order to develop the existing pavement design theory better, the existing cement concrete pavement design specifications are systematically analyzed and the reliability of pavement structure is defined and discussed. The fuzzy random reliability theory is used to systematically analyze the reliability design of the cement concrete pavement structure. The design formula of the random reliability of the pavement is proposed, the variability of each design variable is discussed, and the detailed design is proposed based on the concrete design Steps and ideas.
