水泥混凝土路面的可靠度分析

lot of uncertain factors exist in the course of design, constructing, and management of cement concrete pavement. In order to consider the uncertainty, traditional safety coefficient is substituted for reliability in new Design Code of Cement Concrete Pavement, which makes the concrete pavement design more rationalization. This article analyses the variability and distribution of the random variable. It calculates the reliability of a road by programs, regarding the main structure parameters influencing the reliability of cement concrete pavement as the random variable, using the fatigue probability analysis model.
