Research Of The Expansion Of Three Gorges Navigation Capability

The changjiang river is important transportation link as the connection of theinterior in western China and coastal areas,To promote economic and socialdevelopment plays an extremely important role,Focus on the Yangtze river valley megacities such as ShangHai, NanJing,WuHan,ChongQing,Relying on the Yangtze rivereconomic belt along the Yangtze river to form is the most dynamic and competitive areain our country,The Yangtze river has become the most navigable river in the world.Itimprove navigation condition of the upper reaches of Yangtze River after the threegorges project construction,But insufficient capacity of three gorges ship lock hasincreasingly become the bottleneck of the Yangtze river upstream area shippingdevelopment,It will bring adverse impact the upper reaches of Yangtze River ofComprehensive transportation pattern, the industrial development of the Yangtze riverupstream area layout and the regional economic and social development.This paperaims to though the three gorges ship lock design indicators, management status,transportation demand analysis,put forward the possibility of expansion of the threegorges ship lock and the main measures and solutions.The main cnclusions of this study is:①Analysis of the three gorges ship lockengineering main design parameters,It will focus on the main design parameters ofnavigation structures as well as the overall layout of navigation structures,Lock statusquo of the optimization of design parameter selection.②Operation mode of three gorgesship lock design, ship lock operation index, design on behalf of the ship type, rate, thethree gorges ship lock, three gorges navigation lock time, lock chamber area utilization,brake time interval operation indexes such as compared with the actual operationsituation,Analysis of existing problems, and put forward optimization measures.③Itanalysis research about the present situation of three gorges ship lock the transportgoods, loading coefficient, convection coefficient, variety of goods, carries.④Researchand analysis of three gorges navigation requirements,According to the regionaleconomic development, regional economic development level and characteristics of the upper Yangtze river, the Yangtze river upstream area industrialization judgment anddevelopment trend, the upper Yangtze river region urbanization level and developmenttrend, the three gorges project lock cargo demand influence factors, and integratedtransport development right brake cargo demand influence factors, such as analysis, putforward the upper Yangtze river freight demand, to forecast the future goods passing thethree gorges ship lock in the card, and validate the result of the forecast from variousangles.⑤According to the demand forecast, put forward temporary expansion measures,mainly including: promote the standardization of vessels passing, large-scale, promotion"three gorges ship type", limited passenger ship lock, continue to gradually improve thetonnage of vessels passing limit threshold depth of the water; Optimization of ship lockoperation scheduling; Improve shipping cubed out; Rational utilization of ship lift,etc.⑥Analysis of long-term demand solutions, including railway, highway diversionscheme, a new line lock scheme;⑦Relevant guarantee measures are put forward and thepolicy measures taken by the government departments at all levels.
