大黑汀水库入唐渠与沙岭沟站流量比测分析

Analysis on the Flow Ratio of the Daheiding Reservoir in the Tang Channel and the Shaling Valley Station

引滦入唐工程从滦河大黑汀水库引水输入唐山市市区,供城市生活和工农业生产用水。沙岭沟站为引滦入唐水量监测辅助站,通过对大黑汀水库入唐渠与沙岭沟站野外断面水准测量及监测流量数据分析两站流量关系,率定沙岭沟站水位~流量关系曲线。结果表明在流量稳定情况下,下游的沙岭沟站较上游大黑汀水库入唐渠站基本没有水量损失,符合渠道特性。定线方法及定线精度满足规范要求,沙岭沟站水位~流量单一曲线可以作为引水计量辅助参考依据。

The water diversion project from Daheiting reservoir of Luanhe River Diversion input Tangshan area for the city life and utilizationof the industrial and agricuhural water. Shaling valley station is the auxiliary station of water monitoring. The article is based on analysis of the two station relationship between Daheiting reservoir into Tang canal and Shaling valley field cross-section water levelling and discharge monitoring data, calibrate the relationship between the water level and discharge of Shaling valley. The results show that in the steady flow condition, there is no vcater lost in the downstream of Shaling station than the upstream station Daheiting reservoir drainage station in Tang Channel and is in line with the channel characteristics. Alignment method and alignment accuracy can meet the specification requirements,Shaling valley station water level and flow of single curve can be used as auxiliary reference for water diversion metering.
