万州长江公路三桥水景工程安全评估分析

Safety Assessment and Analysis of Waterscape Project of Wanzhou Third Yangtze River Highway Bridge

如何评估水景工程对桥梁结构和使用安全的影响,目前尚未有统一方法。文中针对万州三桥景观设计需求,结合长江两岸桥头公园绿化、桥头堡造型、夜景色彩,对在主桥钢箱梁范围内设置水景工程方案的安全性进行评估分析。综合考虑水景荷载对主梁的受力影响、潮湿环境对钢箱梁耐久性影响、水景开启对桥下通航和桥上行车安全影响,阐明了在该桥上实施水景工程的可行性。

There is not yet a unified approach to assess the impact of waterscape project on the bridge structure and the use of safety.In response to the needs of landscape design on the Wanzhou Third Yangtze River Bridge,combined with the greening of the bridge head on both sides of the Yangtze River,the shape of the bridge head,and the color of the night scene,waterscape project security programs within the range of the main steel box girder is assessed and analyzed.Considering the impact of the waterscape load on the main beam,the influence of the wet environment on the durability of the steel box girder,and the impact of the water view on the navigation under the bridge and the safety of the bridge,the feasibility of implementing the waterscape project on the bridge is clarified,which has important reference for future bridge landscape design and safety assessment.
