中文摘要：

为研究系杆拱桥在施工过程吊杆索力变化规律，依据兰新二线乌鲁木齐河特大桥1/16缩尺模型试验，针对系杆拱桥吊杆张拉过程进行模拟实验研究，对比常见的2种跳跃式张拉顺序，揭示系杆拱桥吊杆在张拉过程中索力变化规律，经过综合分析张拉方案2优于张拉方案1。同时建立该桥有限元模型，经对比分析得到一致的规律，对同类拱桥的设计和施工控制提供了可借鉴的试验依据。

英文摘要：

In order to study on tension variation of tied arch bridge in the construction process,basis on the1/16scale mode test of the Urumqi River Bridge in the second railway about Lanzhou to Xinjiang,the modelexperimental study is made about tensile process of tied arch bridge.Two kinds of suspender tensioning schemeare compared.The result show the tension variation of tied arch bridge in the construction process and that tensionscheme two is better than the tension scheme one.At the same time,the FEM numerical model of tied arc bridgeis established and its result is analyzed against the experimental data,which show the similar trend.Theconclusion could provide some valuable experimental reference for the design of the same type of arch bridge andits construction control.
