摘要
天津富民桥主桥为单塔空间索面自锚式悬索桥,其主跨主缆采用三维空间线形。在体系转换的过程中,主缆不仅产生垂直方向的变位,还会产生横向变位,猫道位置也需作出相应调整。主要介绍猫道架设与调整方法。
The main bridge of Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge and the main cables of the bridge over the main span are of the three-dimensional geometric shape. In the process of system transformation, the main cables will not only cause displacement in the vertical direction, but also the displacement in the transverse direction and the positions of the catwalk have to be accordingly adjusted. In this paper, the construction methods for erection and adjustment of the catwalk for the bridge are mainly described.
