长江干线大桥水域通航环境安全评价

Safety Evaluation of Navigation Environment in Adjoining Waters of Bridges over the Yangtze River

随着经济的发展,长江干线上建桥越来越多,跨江大桥对船舶航行安全造成了一定的威胁。通过建立长江大桥水域通航环境危险度评价指标体系,根据各指标对安全影响程度的研究结论和专家调查结果,确立通航环境危险度评价标准,并应用模糊综合评价的方法实现对桥区通航环境危险度的综合评价,从而掌握桥区通航环境的安全状况。

With the development of economy, more and more bridges, which threaten traffic safety greatly because of making channel narrow and deteriorating navigation environment, were built over Yangtze River. Based on the theory and method of safety system engineering, the method of fuzzy comprehensive evaluation is applied to safety evaluation of navigation environment in water adjoining bridges. The safety analysis and safety evaluation have practical value for confirming the navigation environment level of danger degree in adjoining water of the Wuhan Yangtze River bridge and danger status of every evaluation factor and providing scientific basis of decision for improving the navigation environment in the adjoining water of the Wuhan Yangtze River Bridge.
