摘　　要：广西百色水利枢纽通航设施工程率先采用“省水船闸+升船机+辅助船闸”组合式通航建筑物总体布置方案,其省水船闸带两级独立梯形断面省水池,省水率可达55%。介绍百色水利枢纽通航设施工程通航建筑物形式选择,阐述采用“省水船闸+升船机+辅助船闸”组合方案后,船闸下泄水流进入中间渠道后引起的升船机上游水位波动情况,以及全平衡式升船机在对接过程中对于水位变化的要求。为解决水位波动对升船机安全运行的影响问题,提出非省水船闸+泄水外排方案与省水船闸方案,并对两方案进行技术经济对比分析,最终确定采用省水船闸方案。Baise water conservancy hub navigation facilities project in Guangxi takes the lead in the navigation building layout using a combination of“water-saving ship lock+ship lift+auxiliary ship lock”,with a water-saving ship lock that includes a two-level independent trapezoidal section water-saving pool,which can save up to 55%of water resources.We introduce the selection of the type of navigation building for Baise water conservancy hub navigation facilities project,and explain the water level fluctuations caused by the discharge flow of the ship lock into the middle channel after adopting the“water-saving ship lock+ship lift+auxiliary ship lock”combination scheme,as well as the requirements for water level changes during the docking process of the fully balanced ship lift.In order to solve the problem of the impact of water level fluctuations on the safe operation of the ship lift,we propose two schemes including non-water-saving ship lock+water discharge scheme and the water-saving ship lock scheme,and compare in terms of technical and economic aspects to determine the water-saving ship lock as the finally scheme.
