摘要
以我国现行路面设计规范为依据，对不同交通等级的典型路面结构的厚度计算结果进行了较全面的可靠性分析，认为规范反映路面结构可靠度的各系数取值，对于特重和重交通等级是适当的，但对于中等和轻交通等级可靠度偏低为明确反映规范方法中隐含的结构可靠度水平，建议以动荷系数和可靠度系数代替现行规范中的综合影响系数。并后分析了主要设计参数的取值及其变异水平对路面结构可靠度的影响。
Thicknesses of typical pavement structures determined by design specification fro cement concrete Pavement on gighway are used for eiliability analysis.Results show that the values of the factors reflectin reliability of strutufe in the specificaytion are well suitable for very heavy and heavy traffic level pavement ,and somewhat small for medium and light traffic level. It is recoended that dynamic factor and reliability facyor is introduced to sub-stitute for the existiong general factor to reflect clearly stuctural reliabilibigy level hided in the design procedure of specification.Finally,effects of mean and coefficient of variation fo basic design parameters on reliability of pavement structure are analysed.
