摘　　要：山区河流改扩建船闸受枢纽坝区河势等条件限制布置难度大,相应通航水流条件较差。采用整体定床物理模型试验对依托工程沅水洪江改扩建船闸上游通航条件进行了研究。阐述设计方案工程布置条件下船闸通航条件及影响因素,针对设计方案船闸通航水流存在的不足,提出延长上游导流堤、调整透空堤范围、调整航线等改善措施,较好地解决了山区河势受限段改建船闸通航问题,可为同类项目提供借鉴参考。It is difficult to arrange the locks in mountainous rivers because of the river regime and other conditions , and the navigation flow conditions are poor. The navigation condition of the upper reaches of Yuanshuihongjiang shiplock for reconstruction and expansion was studied by using a fixed-bed physical model test. In this paper, the navigation conditions and influencing factors of the lock were expounded under the engineering layout of the design scheme, and the improvement measures such as extending the upstream diversion dike, adjusting the scope of the permeable dike and adjusting the route were put forward aiming at the deficiency of the navigable flow of the lock under the design scheme. It can solve the navigation problem of rebuilding ship lock in restricted section of mountain river, and can provide reference for similar projects.
