高水头船闸输水阀门面积对其他水力参数的影响

Influences of the Area of Filling & Emptying Valve for High-water-head Shiplock to Other Hydraulic Parameters

输水阀门面积的大小影响着输水系统的多方面性能,葛洲坝船闸选用的面积当时考虑设计通过能力要求和远景发展,参照国内外的经验及模试情况确定的5.0×5.5m(宽×高)尺寸是合宜的,设计基本合理,文中就输水阀门尺寸的选择计算作了一些分析,以供今后船闸设计时参考和作进一步探讨。

Area of filling & emptying valve of shiplock affects many properties ofthe filling & emptying system. In selection of valve area of Gezhouba Shiplock,not only requirements of design throughput capacity and long-term developmentwere considered, but also experience and model tests of both home and abroadwere taken as reference. At last, it was determined to be 5.0×5.5m(width×height), which was proved to be proper in dimensions and basically reasonablein design. Further analysis is carried out to selection & calculation ofdimensions of filling & emptying valve, so as to provide reference materialfor future design of shiplock.
