Jialing River Chongqing To Beibei Sector Cross River Bridge Ship Collision Risk Analysis

The risk analysis most is earlier than the 20th century 50-60 ages starts to apply in during the European and American Nuclear power plant secure appraisal, afterwards in the developed industrial nation such as chemical industry, the environmental protection, astronautics project, the health, the transportation, the economy and so on the multitudinous domains can promote and the application.In recent years, the risk analysis method day by day was also bringing to people's attention in the ships collision domain research and the application. The bridge ship collision the risk assessment is involves the hydrology, the port navigation, the risk, the bridge and so on many domain interdisciplinary studies. question.Recently several serious ships hit along with our country collapse the bridge accident occurrence, the bridge ship collision the question also more and more to receive the government department as well as the bridge owner and the design department's attention.This article studies the mentality mainly to use present design concept and the design strategy all quite perfect United States standard method.Through to the Jialing River basin partial bridge basic situation investigation, collision the risk rank to the Jialing River Chongqing to the Beibei sector bridge ship to carry on the synthesis classification, obtained the existence to compare the steamship to collision the risk several bridges, and selected the representative bridge to carry on the ship to collision the risk assessment. Depends on gathers the high speed Dongyang zhen bridge and the Chongqing then railroad Caojiet bridge risk analysis to Chongqing, in detail narrated the risk analysis research technique basic principle and the concrete step, the algorithm which uses, and forecast for the first time the ships are open to navigation the quantity reduce to be open to navigation the quantity on behalf of the fleet.Through this research, obtain the Dongyang zhen bridge, the Caojie bridge and the forward forecast is open to navigation under the density in the near future the bridge year collision frequency, the year collapse frequency, for further carried out the thorough research, carried on the careful ship to collision the security evaluation to provide the basis, also might guard against the ship for the correlation department later bridge to collision the work to provide the reference.
