摘　　要：分析现有钢管混凝土拱桥桥道系结构型式对结构受力的影响,在此基础上提出分段连续的桥道系型式,通过理论分析和模型试验,比较吊杆在受力行为上的差异。通过试验模型的实测与有限元计算结果进行验证,并将模型试验中发现的一些问题加以讨论。This paper analyzes the influences of floor system types of existing concrete-filled steel tube arch bridges on the structural behavior of the bridges. On the basis of analysis, the paper proposes a type of floor system that is to be made continuous by segments and compares the differences of the structural behavior of suspenders of the bridges through theoretic analysis and model tests. The proposed floor system is then verified by measurements of the model tests and finite element calculations, and some of the problems having been found in the tests are also discussed.
