泰州大桥系杆拱预应力刚性吊杆一次张拉模型试验研究

Study on One-time full Tension Model Test of Tied Arch Prestressed Concrete Rigid Suspension Cable of Taizhou Bridge

泰州大桥主孔是一座下承式系杆拱桥 ,为满足引江河工程进度的需要 ,对吊杆进行了设计研究 ,采用了预应力刚性吊杆一次张拉完成的施工工艺。为确保施工安全和质量 ,达到设计要求 ,进行了室内吊杆张拉模型试验 ,得出的技术结论用于指导实桥施工。

The main span of Taizhou Bridge is a through tied arch.Study on the design of the suspension cable and one-time full tension construction technology of prestressed concrete rigid suspension cable are carried out to meet the need of Yinjiang River Project.In order to ensure the construction safety & quality and to meet the requirement of the design, a model test on the suspension cable tension is undertaken first, and the technical result is used to guide the on?site construction of the bridge.
