摘　　要：苏通大桥辅桥为(140+268+140)m三向预应力混凝土连续刚构,主跨跨度大,施工、控制难度高,针对该桥特点,综合介绍大跨度连续刚构施工工艺以及主要施工技术难点和施工技术控制措施,对类似桥梁的施工起到借鉴作用。The auxiliary bridge of Sutong Bridge is a concrete continuous rigid-frame structure of three-way prestressing with span arrangement （140＋268＋ 140） m and the main span of the bridge is long, the construction and construction control are difficult. In the light of the characteristics of the bridge, this paper describes in a summarization way the construction technology, principal construction technical difficulties and technical control measures of the long span rigid-frame structure. The descriptions in the paper may serve as reference to the construction of similar bridges.
