摘　　要：缩短吊杆张拉施工工期和避免混凝土梁开裂是先梁后索施工的混凝土自锚式悬索桥施工控制中需要研究的重点内容。介绍湖州市飞凤桥吊杆张拉实施方案,为混凝土自锚式悬索桥施工控制提供借鉴。To shorten the construction time schedule for tensioning of suspenders and to avoid cracking in concrete stiffening girder are the important contents required to be well researched in the construction control of a self-anchored concrete suspension bridge whose girder is to be erected first and main cables are to be installed afterwards. In this paper, the implemented construction scheme for tensioning of the suspenders of the Feifeng Bridge in Huzhou City is presented for reference to the construction control of similar concrete suspension bridges.
