摘要
天津富民桥主桥为主跨157.081 m、边跨86.4 m的单塔空间索面自锚式悬索桥。主跨主缆为三维空间线形,在立面及平面的投影均为抛物线。空间缆索系统在设计过程中,尤其是对多个关键节点构造施工过程中各影响因素的控制方面面临着诸多技术问题。简要介绍该桥空间缆索系统的关键技术。
The main bridge of Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge with a main span 157. 081 m and side span 86.4 m, and the main cables of the bridge over the main span are of the three-dimensional geometric shape whose projection in elevation and in plan is parabolic. In the design of the spatial main cable system of the bridge, lots of the technical problems were to be confronted, particularly with regard to the control of various influential factors in the construction process of several key structural nodes. In this paper, the key techniques for the spatial cable system of the bridge are briefly described.
