摘　　要：随着城市的发展,城区桥梁建设不仅需要满足基本交通功能,还需要与城市周边环境相协调,满足人们的审美需求,而城市的发展离不开景观桥梁的点缀,景观桥梁的建设为城市发展添加了色彩,这就要求在传统桥梁选型的基础上,增加一些景观造型和艺术色彩。文章以海安上湖栟茶运河上的一座钢结构曲线景观桥梁为例,从设计的角度出发,研究小半径曲线钢箱梁设计方法,包括钢箱梁基本参数确定、钢箱梁计算、支座脱空处理等,旨在为类似工程提供借鉴。With the development of the city,the construction of urban bridges not only needs to meet the basic traffic functions,but also needs to be coordinated with the surrounding environment of the city to meet people's aesthetic needs.The development of the city is inseparable from the embellishment of landscape bridges,and the construction of landscape bridges adds color to urban development,which requires some landscape modeling and artistic colors on the basis of traditional bridge type selection.Taking a steel structure curved landscape bridge on the Bencha Canal in Shanghu of Hai'an as an example,this paper studies the design method of small-radius curved steel box girder from the perspective of design,including the determination of basic parameters of steel box girder,the calculation of steel box girder and the treatment of bearing void,aiming to provide reference for similar engineering.
