摘要
文章结合武广客运专线140m钢箱系杆拱桥工程实例,介绍了大跨度钢箱系杆拱桥施工控制的计算方法以及线形监测和应力监测的方法。监测结果表明,成桥线形和应力与理论值一致,证明该施工控制方法和思路取得了较好的效果。
Taking the steel box tied arch bridge with a span of 140 meter in Wuhan- Guangzhou passenger express line as example, the article introduces the calculation method and linear and stress monitoring method.The monitor results show that line shape and stress is consistent with theoretical value.It proves that construction control method has attained great results.
