闽江水口枢纽坝下水位治理工程通航船闸输水系统布置及水力计算分析

Arrangement and hydraulic computation of the lock filling and emptying system of the downstream water level regulation project for Shuikou hydro-junction

闽江水口枢纽坝下水位治理工程通航船闸长宽比达到16.7∶1,且要求输水时间较短、水力指标较高。根据《船闸输水系统设计规范》和该船闸的具体特点,确定了输水系统形式及各主要部位的尺寸和细部布置,对输水系统的水力特性、输水阀门工作条件及闸室和上下游引航道内的船舶停泊条件进行了计算分析,水力计算表明:设计的输水系统各项水力特性均满足规范和设计要求。

The length-width ratio of the navigation lock of downstream water level regulation project for Shuikou hydro-junction reaches 16.7：1,and the filling time is required to be short,the hydraulic indexes are required to be quite high.According to the Design Code for Filling and Emptying System of Locks and the practical situation,the type of filling and emptying system of this lock is put forward,the main dimensions and detailed layout are designed,the hydraulic characteristics,valve＇s working conditions,and vessel＇s berthing conditions in lock chamber and upstream and downstream approach channels are all computed and analyzed.The results indicate that all the hydraulic characteristics satisfy the requirements of the code and design.
