通航河流桥梁主动防船撞措施探讨

Study on measures of ship initiative collision protection of bridge on navigable river

文章从影响通航条件的主要因素,即建桥对通航条件的影响入手,从桥梁选址、桥跨及墩位布设以及通航净空尺度等角度,全面分析了预防船撞桥事故发生的相关措施和技术要求,提出了从桥梁设计角度如何实现桥梁主动防船撞的方法,其成果可为桥梁设计借鉴参考。

Based on the effects due to bridge building which were the main factors of river navigation conditions including the selection of bridge location, the layout of the bridge span and piers, the navigation clearance and so on, the relevant technical requirements and the preventive measures of ship-bridge collision accidents were analyzed comprehensively in this paper. Then the methods for active protection of ship collision from the bridge design viewpoint were proposed. The achievements can be taken as the reference for bridge design.
