船撞效应分析在船舶碰撞桥梁隐患治理中的应用
Application of ship collision effect analysis in the treatment of hidden danger of ship-bridge collision
摘要
Abstract
With the improvement of channel conditions,the tendency of large-scale for ships and the increase of water traffic flow in the lower reaches of the Yangtze River,anti-collision requirements of navigable bridge span and pier raise obviously,anti-collision facilities are needed to be added for some old bridge.The ship impact force of a bridge pier with and without anti-collision facility was calculated with the software LS-DYNA and empirical formula respectively in this paper.The dissipation effect was evaluated for the designed anti-collision facilities,the limiting conditions were selected and recommendations of bridge operation management were offered.The results obtained by this paper can be used as the reference for the anti-collision facility construction of old bridges.关键词
