沙河大街单肋拱桥吊杆张拉施工控制

摘要

以沙河大街单肋拱桥施工为工程背景，介绍了该桥吊杆张拉施工中的吊杆张拉方案，对拱肋位移、主梁位移、吊杆索力等施工控制过程进行了研究，并分析了施工控制结果，为同类型桥梁的建设和吊杆张拉提供了参考。%Taking the construction of Shahe street single rib arch bridge as the project background,this paper introduced the suspender tension scheme of this bridge in suspender tension construction,researched the arch rib displacement,main girder displacement,suspender cable force and so on,and analyzed the construction control results,provided reference for the same type bridge construction and suspender tension.
