Research On Active Measures For Ship To Avoid Colliding With Inland Bridge In Constructing Period

As the rapid development of water transportation in China, more and more various bridges engineering and other water transport project across the navigable rivers. Bridge cross the river or sea are facing the risk of ship collision, navigation safety incidents often happens in bridge area, because the construction bridge engineering has great impact on ship's navigation environment. Statistics show that in recent decades, more than 100 incidents of ships pile up the bridge in the world, in China, the Changjiang River Bridge in Wuhan has happened more than 70 Bridge Collision incidents. From 1960 to 2002 overseas, the ship strike the bridge collapse or serious damage has over 32 incidents, it's about a large bridge was seriously damaged by ships each year in average. Therefore, it has great economic and social value to research on the problems of prevent the ship strike the bridge engineering.In China, the ship strike the bridge happened frequently in bridge area, while construction of the bridge relative to the operation of the bridge has its particularity, its greater impact ship navigation environment, which includes hydrology, meteorology, human factors, construction factors and Bridge District water past the ship and many other risk factors, so the construction of river bridges in his face greater risk of ship collision. Of river engineering, construction of anti-ship collision problem is that the successful construction of bridges and construction of an important guarantee for safe navigation of ships, anti-ship collision is an important part of the study, present research on the river bridge construction bridge waters of anti-ship collision Little work related issues.The paper research the Safety Status of the water transportation in bridge area, research on ship collision risk, application of risk identification risk of ship collision with the construction of source identification, fuzzy comprehensive evaluation model for risk assessment, risk assessment the conclusion that the security level of the bridge project, so we can better understand and master bridge navigable waters of the extent and indicators of environmental risk factors and dangerous situation.To current domestic and international problems of ship collision on the bridge of the bridge most of the work or from the point of view, mainly to focus on the research vessel on the piers of the impact force and energy, make impact piers against ship design standards and the corresponding collision devices in these areas. This paper bridges the research status of anti-ship collision, put forward the initiative to bridge crash, from ships, bridges and people to analyze three aspects, passive crash into the bridge from the bridge of active anti-collision, and finally crash through the bridge take the initiative to study hydrological, meteorological and other risks could cause the elements of ship collision early warning forecasting.This conclusion will provide the basis and reference for decision-making to the maritime management department for organizing traffic flow in bridge area, manage and control the environmental of navigation and safety management.
