Research On Navigation Restrictions And Navigation Safety Guarantee Measures Of The Shuifu Wharf

Mountain river flow commonly urgenter, water surface slope is very steep, rugged terrain and the river twists and turns, secondary flow tend to produce all kinds of bad flow pattern, serious obstacles to navigation. In recent years, with the rapid development of economy, there are many cross river, Kanawha building, navigation and navigation conditions changed greatly, may be on the channel scale, navigable flow condition and the influence of ship navigation safety, if not timely research and take the corresponding protective measures, once a problem occurs, the consequences will be very serious, it is difficult to estimate the economic loss and social influence. Through the actual ship test and physical model test, the navigation conditions of ship mountain port river, and puts forward the shipping security measures corresponding to the test results, provide a reference for solving the similar navigation. The main research contents in this paper and the results obtained are as follows:(1) the ability of beach on ships from the point of view of mechanics, the ship sailing ship thrust power and beach as a key index ships on the beach, in the real ship test process of measured flow value fitting the calculated results;(2) for the water Fuyang River special circumstances, according to the actual situation of the real ship test7000m3/s flow grade, observing and recording the ship sailed all load conditions the maximum rudder angle, the maximum drift angle and track line, with the ship before the beach ability index, analysis of vessel restricted navigation conditions;(3) according to the special conditions of mountainous rivers navigable river port, a detailed study of the port waters by turning physical model test, the scheme of multistage flow conditions, the navigable flow characteristics analysis, the focus is alternative port U-turn waters and optimization scheme of the technical feasibility study;(4) according to the real ship test and the head waters model results, for ships navigation mode, and puts forward the port ship operation and navigation safety guarantee measures.The research results of this paper provide the research ideas and methods for solving similar mountain port river shipping safety problems, especially the ship sailing resistance and thrust as beach ship navigation capability, greatly improve the port navigation conditions of limited theoretical level, the research results is of great value in use.
