摘　　要：为了提出更为科学合理的船闸整体布置方案,对沅水桃源枢纽二线船闸扩建工程的左岸、右岸两种方案的通航安全性进行自航船模试验研究。采用1∶100整体物理模型试验,基于小尺度船模技术对处在分汊河道上的航电枢纽布置和通航条件进行研究,分析船模在不同流量下的舵角、航速等通航参数,结合左汊、右汊水流条件,比较船闸分别布置在左岸、右岸方案船舶的通航情况,提出采用右岸通航方案作为新建二线船闸的整体布置方案。开展小尺度船模试验直观展现了船舶在不同汊道中的航行情况,为解决该类工程的通航汊道选择问题提供了技术支撑。In order to put forward a more scientific and reasonable overall layout scheme of ship lock,the navigation safety of left and right bank schemes of the second-line ship lock expansion project of Yuanshui Taoyuan Junction was studied by self-propelled ship model test.By using 1∶100 integral physical model test and small-scale ship model technology,the arrangement and navigation conditions of avionics junction on bifurcated river were studied.The navigation parameters of ship model such as rudder angle and speed under different flow rates were analyzed,and the navigation conditions of ships with locks arranged respectively on the left and right banks were compared according to the flow conditions of the left and right branches.The navigation scheme of the right bank was proposed as the overall layout scheme of the newly built second-line lock.The small-scale ship model test shows the sailing conditions of ships in different branches directly and provides technical support for solving the problem of choosing navigable branches in this kind of engineering.
