摘　　要：以全平衡垂直升降为核心的三峡升船机,是目前世界上规模最大、运行条件最复杂、技术难度最高的升船机。在三峡升船机复杂的外部通航环境无法改变的情况下,轨道牵引系统无法安装布置。为提升三峡升船机的通过效率,提出采用推轮顶推的方式实现船舶进出船厢,但必须要面对成组船舶在上下闸首狭窄航道中的低速航行问题。文章主要围绕成组船舶进出船厢时在狭窄水道中低速航行的典型工况,考虑浅水效应、岸壁效应以及船-船间干扰等因素的影响,分析两船的水动力特性和船间干扰力情况,为后续升船机效率提升提供理论依据。The Three Gorges ship lift,with fully balanced vertical lifting as the core,is currently the world's largest,most complex operating conditions and the most technically difficult ship lift.Under the condition that the complex external navigation environment of the Three Gorges ship lift cannot be changed,the orbital traction system cannot be installed and arranged.In order to improve the passage efficiency of the Three Gorges ship lift,this paper proposes to use the pusher boat jacking method to realize the entry and exit of ships,but it is necessary to face the problem of low-speed navigation of groups of ships in the narrow channel of the upper and lower locks.This paper mainly focuses on the typical working conditions of low-speed navigation in narrow waterways when groups of ships enter and exit the ship's compartment,considers the influence of shallow water effect,shore wall effect and ship-ship interference,and analyzes the hydrodynamic characteristics and inter-ship interference of the two ships,so as to provide a theoretical basis for the subsequent efficiency improvement of ship lift.
