摘　　要：以陕西关中某高速公路为例,进行边沟、排水沟、超高路段路面排水沟管的水力计算与分析,得出不同断面尺寸、不同填挖状况下,边沟、排水沟的排水能力与沟底纵坡的相关关系,提出边沟、排水沟以及超高路段路面排水沟管设计时的断面尺寸、出水口间距的参考取值,为高速公路排水设计人员进行科学合理的设计工作提供计算实例.Taking a highway in Shanxi Guanzhong as an example,this paper carries out hydraulic calculation and analysis of the side ditch,the drainage ditch and the drainage pipe of superelevation section to educe the correlational dependence of drain flow capacity on the longitudinal slope of ditch bottom under the condition of different cross section size and different fill or cut section,and to propose the reference value of the cross section size,the water outlet spacing of the side ditch,the drainage ditcht,herefore provides the computation example on the science reasonable design work for personnel who engaged in the highway draining water design.
