摘要
目前组合式排水口在城市道路路表排水系统中应用得并不广泛。利用水力学原理及经验公式,对不同形式的边沟流量和组合式排水口在连续坡度上及凹形竖曲线底部的排水能力进行了水力计算,并采用修正法计算了不同形式的边沟水流量。对组合式排水口的水力计算,综合考虑了边沟形式、边沟内水流量、铺面横坡、道路纵坡等因素,得出了组合式排水口排水能力的计算公式。
At present,the application of combined outfall in urban road surface drainage system is not wide.It uses the hydraulics principle and empirical formula to calculate the flux of different forms of side ditches and the drainage capability of combined outfall at continuous slope and concave vertical curve bottom,and uses mod-ification method to calculate water flow of different forms of side ditches.The hydraulic calculation of combined outfall takes comprehensive consideration of factors such as side ditch form,water flow inside side ditch,pave-ment lateral gradient,etc.,thus the calculation formula of water drainage capability of combined outfall is concluded.
