摘要
指出大跨径连续箱梁悬浇施工时,挠度的控制直接影响桥梁成桥后的质量与正常使用状态下的线形,结合挂篮悬浇施工的实践,介绍了影响挠度控制的主要因素及箱梁施工过程中的挠度控制方法,以达到最佳控制效果。
This paper points out that the control of deflection during large-span continuous box-girder cantilever construction directly influences the quality of bridge and the bridge linear under normal utilization.Combined with practical cradle cantilever construction,it introduces main factors influenced deflection control and deflection control methods during box-girder construction process,in order to gain optimal control effect.
