韩江东山枢纽二线船闸通航条件试验研究

Study on navigation conditions of the second line ship lock of Dongshan water conservancy project in Hanjiang River

东山枢纽已建设一座300 t级的船闸,根据韩江三河坝至潮州港航道扩能升级工程的需要,新建1 000 t级二线船闸。采用整体定床物理模型试验与自航遥控船模试验相结合的技术手段,选用1:80的正态比尺,对东山枢纽的天然水流特性、新建二线船闸设计方案、修改方案的通航水流条件、船舶航行条件进行了试验,从水流指标、防洪影响等方面进行了综合分析,提出了满足要求的推荐方案。研究结果表明:推荐方案实施后,能够满足各种工况下船舶通航要求,不会对防洪、发电产生不利影响。

It has been built 300 t ship lock in Dongshan water conservancy project. According to the needs of the Hanjiang Sanhe dam to Chaozhou port waterway expansion and upgrading project, a new 1 000 t second line lock need to be built. The combination of fixed bed physical model test and self-propelled remote control ship model test were adopted. Using the normal scale of 1：80, the natural flow characteristics of Dongshan water conservancy project, the navigable flow condition and the ship navigation condition of design scheme and modification scheme of the new second line ship lock were tested. The comprehensive analysis was carried out from the water flow index and the influence of flood control, and recommendation scheme was put forward to meet the comprehensive requirements of all parties. After the recommended scheme implementation, it can meet the requirements of ship navigation under various conditions, and will not adversely affect flood control and power generation.
