水电工程施工区水泥混凝土路面设计方法探讨

摘要

根据现行水电工程施工区水泥混凝土路面设计规范，以水泥混凝土面板疲劳强度作为控制指标，比较了两种设计方法的计算结果，发现按照《公路水泥混凝土路面设计规范》计算所得的水泥混凝土路面结构厚度较厚。通过分析这两种设计方法的差异，提出《厂矿道路设计规范》更适合用来指导水电工程施工区水泥混凝土路面的设计，同时也提出该规范还需进一步完善，以考虑最重轴载对施工区的极限破坏作用。%Based on the current design specification for concrete road pavement in the site of hydropower station, taking the fa-tigue strength of concrete pavement as the controlling index, the calculation results of two design methods are compared. It was found that the thickness of concrete pavement structure calculated by the Specification for Design of Highway Cement Concrete Pavement was thicker. Through the analysis of the differences of the two design methods, it was pointed out that Specification for Design of Factory and Mine Roads ( SDFMR) was preferable for guiding the design of concrete road pavement in the site of hydro-power station. Meanwhile, the further improvement of the SDFMR was needed in consideration of the ultimate damage of the heaviest axle load on the road.
