路基路面排水设计对公路的使用状况尤为重要,排水系统及排水设施的完善与否直接影响公路路基、路面的正常使用寿命。因而,对于设计者来说,应对公路排水设计充分的认识,充分考虑影响排水的因素,针对不同条件采用相应合理的排水设计。本文简要的对公路路基路面的排水结构设计进行了分析,以供参考。 Subgrade drainage design is particularly important for the use of roads. The improvement of drainage system and drainage facilities will directly affect the normal service life of highway subgrade and pavement. Therefore, for designers, should fully understand the design of highway drainage, give full consideration to the factors that affect the drainage, according to different conditions, the appropriate drainage design. This article briefly analyzes the drainage structure design of highway subgrade and pavement for reference.
