大跨拱桥吊杆张拉计算与方案设计关键技术

Key Technology of Tension Calculation and Plan Design of Hanger Rod of Long Span Arch Bridge

经过仔细分析发现,模拟吊杆力的变形量是施加在未变形的结构体系上的,实际工程却是在已经变形的结构上张拉吊杆,直至达到设计值为止。针对此问题,利用ANSYS软件,本文提出温度系数法和吊杆力系数法,并结合厦门五石路桥的工程实例,将之运用于五石路桥工程中,取得满意的工程效果。

Through careful analysis,we found that the deformation of tensile force of rod should exert on nondeformed structure system,but the hanger rod was often used in deformed structure in practical projects until it reached the design value.In view of this problem,temperature coefficient method and tensile force of rod coefficient method were put forward by using software ANSYS to solve this problem in the project of Wushi Road Bridge(a half-through steel arch bridge) in Xiamen city,and a satisfied effect was ob...
