摘要
确保路面结构的使用寿命是当前道路工程领域面临的重要研究课题.在前人研究成果的基础上,通过引入动态可靠度指标和路面结构耐久性设计系数,建立了水泥混凝土路面结构耐久性设计验算模型,该模型与我国现行的《公路水泥混凝土路面设计规范》给出的设计表达式相协调,便于实际应用,并结合应用示例进行验证.
Doing research on the life - span of pavement structure is an important task in the field of road engineering. Based on some former researches, the paper proposes a durability design model of cement concrete pavement through the dynamic reliability index and the durability coefficient. The established model corresponds well with the design expression of the current design specification code of cement concert pavement in China. And it is easy to use for practical application in design. A case study about the durability design method of cement concert pavement is shown in the end.
