繁忙航道上钢结构斜靠拱设计与施工

Design and Construction of Steel Inclined Arch Bridge Crossing Busy Waterway

云梨桥为苏南运河上一座跨径100m,钢结构斜靠拱桥梁。钢结构斜靠拱造型优美、结构合理,传统的斜靠拱均采用在支架上拼装的施工方法,本项目采用分幅浮拖再拼装的施工方法,成功地解决了繁忙航道上的斜靠拱施工问题。

Yunli Bridge is a steel inclined arch bridge in Sunan Canal with the span of 100 meters. Inclined arch bridge is a bridge type with graceful appearance and reasonable structure. Falsework construction is normally used in inclined arch bridge construction. In this project,the bridge is disassembled into two parts transversely which are hauled across the waterway separately by towboat and then assembled. This method is a successful solution of construction of steel inclined arch bridge crossing busy waterway.
