Study On Navigable Two Phase Expansion Project Of ShuiFu Port Of Yunnan Province

In the harbor in the side of jinsha river in yunnan province in fushui county, water in the Yangtze river economic belt, the chengdu-chongqing economic zone, kunming economic belt of the three economic regions overlap alternately, is the only can implement yunnan level is above1000t ship dock with the Yangtze river water transportation main hub port, known as the first port of the Yangtze river golden waterway and yunnan\"north gate\". In the construction of the port, is not only make full use of the Yangtze river golden waterway construction of zhaotong comprehensive transportation network to promote regional development is an important engineering, and construction of yunnan has become an important bridgehead for southeast Asia, South Asia, promote internal opening to the outside is important rely on. In the port of the jinsha river is the upper reaches of the river, the jinsha river is a main river in southwest in China, in order to ensure the jinsha river waterway and port in the smooth and safe production, studies the problems of the navigation is very necessary. This paper aims to pier site selection, general layout, structure design, form a complete set of engineering, port construction, port operations involved the study of navigation problem, put forward the possibility of pier construction and protection and measures to improve navigation.The main conclusions of this study is:①The port navigation conditions are complicated, though a lot of adverse external factors, but the port in accordance with "overall planning" Shuifu port, in adopting the floating bollard, set the stop position mark, establish forecast and information transfer mechanism and other measures, guarantee the safe operation of the pier, the construction of basic feasible.②The wharf harbor waters, waters, berth length cyclotron meet "port engineering master design code"(JTJ212-2006) requirements, but the large area excavation level caused by falling. Design depth of wharf apron should further increase the depth on the basis of the design.③In the ten year flood level, instream flow velocity in the above4m/s, the maximum velocity of up to5.99m/s the main channel, bollard shall be not less than5m/s review on the bollard is.④In order to reduce the Xiangjiaba River unsteady flow, berthing and terminal operation bring great security risks to the ship,, increase the floating bollard in wharf construction, but also with the Xiangjiaba project to establish contact mechanism, establish and improve the forecast and information transfer mechanism.⑤At the same time, taking into account flood velocity is larger, the initial consideration will be8500m3/s as prohibited flow. The additional lateral buoy, cattle and bollards, mooring facilities, in order to ship to berth, and set the project area navigation mark,⑥Safety production scheduling mechanism for the establishment of efficient.
