摘要
三峡—葛洲坝梯级枢纽两坝间航道汛期适航流量标准是大流量时安排船舶过闸计划的依据.在分析两坝间船型现状、枢纽调度运行情况的基础上,根据实测水文资料、数学模型和实船试验成果,对不同水情条件船舶在两坝间河段的航行性能进行综合评估,针对干散货船、液货船和集装箱船提出以满载排水量、主机功率和单位功率装载量为控制因素的适航流量标准.研究结果对两坝间航道的通航管理具有重要的参考价值.
Abstract
The navigable flow of ships in the waterway between the Three Gorges and Gezhouba dams is the basis for arranging the plan for ships to pass through the ship-locks during the flood season.Based on the analysis of the current ship types and dam scheduling operation of the Three Gorges and Gezhouba dams,this paper evaluated the navigation performance of ships under different water conditions according to the measured hydrological data,mathematical model results,and on site ship test.And the navigable flow standards with full load displacement,main engine power,and unit power load as control factors were proposed for dry bulk cargo ships,liquid cargo ships,and container ships.These findings provide valuable information for the navigation management of the waterway between two dams.
