摘　　要：随着我国交通基础设施建设的大力发展,越来越多不同结构形式的桥梁出现在交通体系中,钢管混凝土系杆拱桥由于具有优越的力学性能,在交通建设中运用的越来越广泛。在一条道路的建设中,桥梁往往作为控制性工程制约着工程的建设进度,为保证桥梁在施工过程中安全、顺利建成,对施工技术难度大、施工风险高的桥梁,一般需要进行施工监控工作。文章以铜陵长江大桥北引桥1-96m下承式钢管混凝土系杆拱桥为依托,就下承式钢管混凝土系杆拱桥的施工监控方法进行了研究,具有较大的现实意义和工程应用前景。With the vigorous development of China's transportation infrastructure construction,more and more bridges with different structural forms appear in the highway transportation system,and the concrete-filled steel tube tied arch bridge is more and more widely used in traffic construction due to its superior mechanical properties.In the construction of a road,the bridge is often used as a control project to restrict the construction progress of the project,in order to ensure that the bridge is completed safely and smoothly in the construction process,the bridge with high construction technical difficulty and high construction risk generally needs to carry out construction monitoring work.Based on a bottom-supported concrete-filled steel tubular tied arch bridge,this paper studies the construction monitoring method of the lower-supported concrete-filled steel tubular tied arch bridge,which has great practical significance and engineering application prospects.
