黄河下游堤防道路路面结构型式探讨

摘要

结合黄河下游堤防工程特点和已建堤防道路运行情况，分析现状路面运行过程中产生的病害，并对现路面结构自身存在的问题进行了探讨。通过对堤防弹性模量的合理确定、路面结构层材料的选择、性能和费用合理性进行分析，提出了堤防道路路面结构型式的优化方案。优化的路面结构较原路面结构在建设费用上有所提高，但路面性能有较大程度的改善，可大大提高堤顶交通通行的保障程度，并大幅降低后期养护费用。%Considering the characteristics of the Lower Yellow River dyke projects and the situation of the existing dyke-top roads operation,this paper analyzed the illnesses generated during the operation of the existing road surface and discussed the problems existing in the road surface struc-ture itself. Through reasonable determination of dyke elasticity modulus,selection of road surface structure layer materials and analysis of perform-ance-cost rationality,we optimized dyke road surface structure type. The optimized road surface structure would cost a little higher than the origi-nal structure in terms of construction,but the road surface performance would be improved to a higher level,which could greatly improve the guar-antee level of dyke-top traffic and significantly reduce post-stage maintenance cost.
