八尺江大桥缆索吊装系统安全与稳定性分析

文章以八尺江大桥主桥施工时采用的缆索吊装系统为研究对象,采用通用有限元软件ANSYS建立空间模型,对该系统在自重和吊装重量及风荷载作用下的安全性和稳定性进行分析,得出该缆索吊装系统满足设计吊重的要求,同时详细阐述了该类结构验算的控制因素及各工况的考虑方式,可为同类结构验算提供参考。

Safety and Stability Analysis of Bachi River Bridge Cable Hoisting System

With the cable hoisting system used in main bridge construction of Bachi River Bridge as the research object, the article used the general-purpose finite element software ANSYS to establish the space modeh analyzed the safety and ＇stability of this system under the impact of dead weight and hoisting weight and wind loads, and obtained the require- ments that this cable hoisting lilting system meets the design hoisting weight, while elabo- rating in details the controlling factors of such structure checking and the consideration ap- proach under each working condition,thereby providing the reference for the similar struc- ture checking.
