摘　　要：输水系统是船闸实现其功能的关键设施,其设计直接影响船闸工程的安全与效率。等惯性四区段出水分散输水系统是目前国内外高水头大型船闸常用的输水系统形式,但其结构复杂、建设难度大,且由于设置第二分流口而带来自身空化等问题。为解决上述问题,结合我国内河船闸特点,通过国内外工程资料分析、理论与计算分析、物理模型试验等手段,提出并验证了"闸墙长廊道+闸室中心立体分流+闸底两区段四纵支廊道出水+侧支孔+明沟消能"的等惯性两区段输水系统形式在40 m级单级巨型船闸中的适用性,为高水头大型船闸建设提供参考和依据。As the critical facility of the navigation lock＇ s function achievement, filling and emptying system design directly influences on the safety and efficiency of lock engineering. Four-section total-balanced filling and emptying system is commonly applicated in high-head large locks domestic and forign.However, the system has the disadvantages of complicated structure and high construction difficulty, also the cavitation problem of its secondary divider. There are the characteristics of inland locks in China, the analysis of domestic and international eningeering data, theoretical and mathematical research, physical model experiment to avoid these disadvantages. The feasibility and applicability of the two-section four-manifold total-balanced filling and emptying system with ＂long culvert in lock wall ＋ vertical divider at lock center ＋ two-section four-manifold at lock chamber bottom ＋ side ports ＋ open ditches for energy dissipation＂ has been proved and verified in 40 m-grade single-step giant lock, which provides the reference and basis for high-head large lock designment.
