高等级公路路面集中排水水力计算

Hydraulic calculation for expressway pavement surface drainage

为了提高路面集中排水水力计算的精度 ,笔者通过理论推导 ,从质量守恒出发 ,利用谢才—曼宁公式 ,采用微分法提出了一个计算暴雨时路面集中排水的水力计算方法 ,经比较这一方法使用方便 。

To improve the design of pavement surface drainage,this paper puts forward a new method of hydraulic calculation for pavement.On the basis of the conservation of mass,the paper utilizes the Chezy Mannings theory to analyze the current on the pavement surface and brings forward a few new formulas.The new method is valuable and flexible in practice.
