摘要
良好的排水系统可防止高速公路路面积水,减轻积水对路面的的侵蚀,从而延长公路的使用寿命。因此,优化高速公路排水系统设计是提高高速公路设计水平的重要环节之一,结合邢临高速的统计资料,对高速公路排水设施设计进行了说明,详细介绍了边沟、中央分隔带、排水沟、急流槽的设计,并对高速公路排水设施类型、设计原则做出了总结。
A good drainage system can prevent water from remaining on highway surface and reduce the erosion to pavement, so it can prolong its service life of the highway. Therefore, optimizing the design of highway drainage system is one of the important part of raising highway design level. Combined with statistics of Xingtai-Linxi expressway, this paper describes the design of expressway drainage facilities, details the design of side ditch, medial divider, drainage ditch and chute. Furthermore, summarizes highway drainage facilities＇ types and design principles.
