摘　　要：水泥路面结构的结构参数、使用环境和交通荷载都具有随机性,设计、施工和使用过程中各因素的变异性都会影响路面结构的可靠度。分析了各因素的变异性大小和其对结构可靠度的影响,其中面层厚度、模量与强度以及基层顶面模量是路面结构可靠度的显著因素,施工中应控制这些参数的变异水平。The structural parameters, environmental factors and traffic loads of cement pavement are uncertain,and this uncertainty appearance in the process of designing, constructing and taking service.Distribution and range of variation of these parameters which is decided by the level of construction control have been analyzed. It is proved that flexural strength,thickness of the surface layer and modulus of basic is the significant facts of pavement reliability so the variability of these facts should be controlled.
