基于现行的《公路水泥混凝土路面设计规范》(JTJ012-94),在力学分析的基础上,应用概率方法研究路面结构的安全问题。考虑设计参数的变异性对设计的影响,通过引入可靠度系数把原有确定型水泥混凝土路面结构设计方法改进为可靠性设计方法。并且通过对现有公路的验证,修正了理论可靠度与实际可靠度之间的偏差,使该设计方法更加符合实际路面的使用要求。 Based on the current “Code for Design of Highway Cement Concrete Pavement” (JTJ012-94), on the basis of mechanical analysis, the probabilistic method is applied to study the safety of pavement structure. Considering the influence of the variability of design parameters on the design, the design method of the original concrete cement pavement structure was improved to reliability design by introducing the reliability coefficient. And through the verification of the existing highway, the deviation between the theoretical reliability and the actual reliability is corrected, so that the design method is more in line with the actual road use requirements.
