大跨悬索桥施工索塔变形成因分析与监测
Cause Analysis and Monitoring of Deformation of the Cable Support Tower of Large Span Suspension Bridge During Construction
-
摘要:介绍了大跨悬索桥不同施工阶段索塔变形的成因分析以及索塔变形监测的目的和作用,采用了距离差 监测法进行索塔变形的监测,取得了较好的监测效果,对同类桥型的施工具有较大的借鉴作用。Abstract:The deformation causes of the cable support tower of large span suspension bridge at different construction stages, as well as the purpose and effect of monitoring the cable support tower deformation, are introduced. A distance difference monitoring method is used to monitor the deformation of cable support tower, obtaining a comparatively good result; and can be taken as a good reference for the same kind of bridge construction.
