南水北调配套工程石津干渠渠道水面线计算与分析

Calculation of South-North Water Transfer Project surface line of Shijin main canal

石津干渠因线路较长,控制性水位多由灌溉渠道灌溉水位确定,其下支渠众多,水面线推算是本工程的重中之重。以石家庄市区段为例,对石津干渠总干渠水面线进行推算,经过两年试运行,效果良好。

The Jin trunk canal is one of the inter-city trunk canal projects in Hebei province.Because of the long South-North Water Transfer Project,the controlled water level is mostly determined by the irrigation water level of the irrigation canal,the calculation of water surface line is the most important part of this project.Taking the Shijiazhuang Urban section as an example,this paper calculates the water surface line of the main channel of Shijin Trunk Canal.After two years'trial operation,it runs well.
