摘要
根据葛洲坝和大源渡枢纽船闸多年的上、下游水位资料,对葛洲坝枢纽船闸的工作水头进行统计分析。分析表明：葛洲坝和大源渡枢纽船闸工作水头均值分别是设计水头值的80%～87%以及70%~79%,由此结论进一步对船闸输水系统设计时水头的选取、船闸的通过能力计算等问题进行探讨,提出了采用某一保证率的水头作为输水系统的设计水头及将修正系数引入船闸通过能力的计算公式等观点,可供船闸工程设计及规范的修订参考。
The operation heads of Gezhouba and Dayuandu shiplocks were counted and analyzed based on the data of daily upstream and downstream water level for many years,which indicates that the average operation heads are 80% to 87% and 70% to 79% of the design head respectively.Based on this conclusion,problems such as fixing value of head in filling and emptying system design as well as calculation of shiplock capacity were discussed,views of using guarantee rate of head as the design head in the filling and emptying system design and introducing modified coefficient into the calculation formula of shiplock capacity were submitted.The above conclusions and views may serve reference for shiplock design and code modification.
