【摘要】 节制闸间距的选取影响到工程投资的多少与能否安全运行的问题 .本文以南水北调中线工程初步设计参数为依据 ,从调度的灵活性 ,事故处理时间 ,闸门、渠道的安全超高、水头损失与最低流速及节制闸工程造价等 5个方面讨论了中线干渠节制闸间距长短的优缺点 .通过各种因素的综合分析 ,认为节制闸间距取2 0～ 3 0km为宜更多还原

【Abstract】 The controlling gate interval not only influences the cost of the project but also associates greatly with safety work. In order to confirm the controlling gate interval for Middle Line Scheme of Water Transfer Project from South to North China, analysis of different effects were performed on the base of the initial design data. The analysis include five aspects: first, the agility of dispatching; second, the time for dealing with accident; third, the safety freeboard for the channel and the controlling gate; fourth, the head loss and the minimum flow velocity; and the last one, the cost of the controlling gates. Through the study of all these aspects, a range of distance(20km～30km) was given for the controlling gate interval.更多还原
