摘要
大跨径连续梁桥施工环节多,各环节不可避免会产生误差(偏差),且各类误差(偏差)普遍会随连续梁桥悬臂段的不断伸长而逐渐积累,如不在施工过程中加以控制及调整,将造成大桥合龙困难。本文以某特大桥为例,对连续梁悬臂施工过程进行了深入分析,并提出了具体的线形控制方案。
There are many links in the long-span continu-ous bridge building, Each link will inevitably produce errors （ bias） , and all kinds error （ bias） generally will be accumulate with the elongation of the cantilever section continuous beam bridge, if we do not control and adjustment in the construction process, the bridge closure will very difficulty. Taking a bridge as an example, the construction of continuous beam cantilever process of in-depth analysis, and put forward specific linear con-trol scheme.
