摘要

Being the first to use the inclined special-shaped columns at home,the Dongxu Road Bridge across the Jing-Jin-Tang Expressway in the West District of the Tianjin Development Zone is unique in structural shape,beautiful in form but difficult in construction.With the bridge as a practical example,introduced in the paper are the main construction links and technical measures adopted for the main construction links such as the positioning and setting-out processes of the construction of the inclined columns,the formwork,the processing of reinforcement,etc.,all of which effectively helps ensure the successful completion of the project.As a result,the quality of the finished bridge is fine,and the style of the bridge is beautiful.It may serve as a useful reference for projects of the same type.%天津开发区西区冬旭路跨京津塘高速公路桥为国内首次使用的空间异形斜立柱桥,结构形式独特,造型优美,施工难度大。介绍了并行斜立柱施工中的定位放线、模板工程、钢筋加工等主要作业环节及采取的技术措施,有效保证了工程顺利进行。施工成桥质量良好、桥型优美,对同类工程有参考价值。
