三峡水库蓄水运行以来,库区水运交通日益繁忙,船舶误入白鹤梁水下保护体禁航区的次数增多,作为连接岸边陈列馆与水平保护体的交通廊道所受的威胁增多,需尽快研究完善交通廊道的防撞设施。以趸船、重力式方块堤和钢格构框架为候选形式,运用有限元瞬态碰撞动力学方法,对3种防撞形式的性能进行分析。结果表明,3种方案均满足结构防撞要求,但从施工维护便利性、对水流影响、景观效果等多方面综合考虑,最终推荐采用趸船防撞方案。

After the operation of Three Gorges Reservoir, the water transport is increasingly busy, thus more ships stray into the prohibited area of underwater protection works of White Crane Ridge Inscription. It severely threatens the safety of communi-cation corridor that links exhibition hall on shore and the underwater protection works, so it is required to make an anti-collision solution for the corridor as soon as possible. FEM transient collision dynamics is used to analyze performances of three types of anti-collision equipments, namely the barges, gravity cubic dykes and steel frame. The results show that all the alternative solu-tions can meet the anti-collision demands. The barges solution is adopted considering the construction and maintenance conven-ience, influences on water flow and scenery effects comprehensively.
