摘要
Abstract
With the 175 m reservoir operation of the Three Gorges Reservoir,bridge area navigation width becomes further narrow,water depth increases,and the arch foot elevation is low.Collision of arch and post can easily lead to the collapse of arch bridge when ship is out of control or moving off the channel.In order to prevent the occurrence of such vicious incidents,the construction of bridge anti-collision equipment is particularly important.Taking Wanzhou Changjiang River Highway Bridge as an example,in the design of bridge anti-collision facilities,the research results were quantitatively and qualitatively analyzed by using small scale ship model technology.The changing law of the falling velocity after collision and change law of ship possibility in different position of the collision avoidance zone were presented.The reliable data and theoretical guidance were provided for the design optimization.关键词
