The Study On Definition Of Bridge Water Area In Tide River

With the rapid development of China's shipping industry, its growing role in promoting economic development, the Yangtze River, Pearl River and other waterways have become an important regional economic artery for blood transfusion, how to solve a waterway navigable waterway bridges impact on more and more attention reasonable definition of the correct assessment of the bridge bridge navigable waters of the impact and maintain its own security is important bridge.The definition of waters of the bridge, the bridge is located in a large extent by the hydrological conditions of water courses, water conditions change periodically over time, sailing in the navigation channel impacts are occurring cycle of travel, impact on navigable waters bridge security and personal safety directly.Many rivers in our country are east into the ocean, the hydrological conditions of these waterways is not only the seasonal precipitation caused by climate change impacts, while the role by the ocean's tidal flow movement caused by a short period, even in some tidal potent rivers, estuaries, tidal hydrological conditions as a major factor. In the tidal reach waters within the definition of a bridge a bridge, not only to analyze the hydrological conditions of the region's seasonal line changes, taking into account the hydrological changes caused by tidal action, and the two superimposed.This paper is divided into seven chapters, Chapterâ… is an introduction, Purpose of the study, meaning and related studies. Chapterâ…¡is analysis of navigable tidal river hydrological conditions, Introduction of the main causes of the tides and the tidal reach of the water level navigation features. Chapterâ…¢is the define of bridge water area based on f ship handling performance, mainly from the perspective of the ship bridge control to get the mathematical model. Chapterâ…£the define of bridge area based on ship drift, Mainly from the ship drift by wind and water flow affect to get the mathematical model of the define of bridge waters Chapterâ…¤is the Verification of the mathematical model, to Huaneng Nantong Power Coal trestle as an example, To verify the the mathematical model in chaptersâ…¢andâ…£. Chapterâ…¥is the Significance and effect of the define fo the bridge water area, the actual meaning and role on the bridge water area in navigable security. Chapterâ…¦is Summary and Outlook, to summarize the problem in the writing this paper.The purpose of this research is to get a method of the bridge water in tidal river, so as to Provide a scientific basis for decision making and reference for the definition of waters of the bridge and navigation management and maintenance of t bridges own safety by MSA.
