高速公路中央分隔带排水设计研究

Drainage design of the central reserve on speedway

通过对高速公路中央分隔带的设置型式、功能、内部积水的原因及其对路面结构、路基造成损害和对行车的影响程度进行简述 ,指出高速公路进行中央分隔带排水设计的必要性 ;结合中央分隔带排水设计原则 ,提出关于设计要点的构思、设计方案的布置及其排水构造的设计要求 ;并对各种设计方案进行综合评价 ,供同类工程设计参考。

The function and setting style of the central reserve on speedway are described as well as the cause of its interior accumulation of water,the degree of this damage to the road surface frame and roadbed,and the influence of such ponding on driving of vehicles.It is necessary to carry out drainage design of the central reserve on speedway.The main design ideas of the central reserve,the layout of the design scheme and the design demand of the drainage structure are presented based on the principle of drainage design of the central reserve. Various design schemes are evaluated comprehensively,which may be helpful to similar designs in practical engineering.
