摘要
感潮河段支流口门建设调水工程时,枢纽受到用地条件限制常距江较近且开敞布置,引水和排涝受到外江非对称涨落潮流牵制,流态十分复杂,节制闸、泵站和船闸建设协调困难。针对新孟河延伸拓浚工程界牌枢纽工程,进行枢纽整体水流条件研究。结果表明:界牌枢纽受到外江不同涨落潮条件和节制闸、泵站不同引排水工况的影响,局部形成不良流态,枢纽布置时应采取相应的优化措施。
The hydro-junction for water diversion project located at branch entrance of the lower tidal reach usually faces flow condition problem through sluice gate.Due to limited land conditions,the hydro-junction has to be built closed to the main river outside the branch entrance and keeps an open layout.As a result,branch mouth flow is significantly affected by the asymmetric tidal flow of main river and the cross flow at the entrance area of the sluice gate.Based on Jiepai junction,downstream and upstream flow condition is studied.
