STUDY ON THE PRINCIPLE OF PLANE LAYOUT OF THE SECOND-LINE SHIP LOCK EXTENSION PROJECT OF NAVIGATION POWER JUNCTION IN INLAND RIVER

摘要

The development of shipping makes the ship lock of navigation power junction in inland river change from single-line into multi-line. Ship lock expansion is conditioned by multiple factors such as key projects, navigation planning, land expropriation and construction investment etc., which increase the difficulty in plane layout. Based on the second-line ship lock extension project of Zhuzhou Navigation Power Junction, the layout plan of ship lock expansion is analyzed in this paper by employing overall hydraulic model, self-propelled ship model, 3-D flow numerical simulation and other technical means. The effect laws of the position of ship lock extension project and the type of approach channel and other layout parameters on the navigation condition of ship lock and berthing condition within approach channel was analyzed. Furthermore this paper also summarizes the principles that plane layout of the second-line lock extension project of navigation power junction in inland river should follow based on the plane layout characteristics of ship lock extension project of other domestic key projects.
