小溪塔大桥斜拉悬臂桁架梁施工技术要点

Construction Techniques of Cable-stayed Cantilever Truss Beam

宜昌市夷陵区小溪塔大桥是国内主跨跨径最大的预应力混凝土斜拉式桁架连续刚构桥。介绍了该大桥的设计特点和运用悬臂浇筑法进行大桥施工的技术要点,为类似工程提供借鉴。

This paper mainly introduces the prestressed concrete cable-stayed-truss continuous rigid frame work-Yichang Xiaoxita Bridge, which is the largest in terms of the main span in China. The design features the bridge tower, because it is the first Successful use of the cantilever pouring construction techniques, and therefore will be adopted for similar projects as a reference.
