钢管混凝土拱桥静载试验方法研究

Study on Static Load Test Method of Concrete Filled Steel Tubular Arch Bridge

钢管混凝土拱桥以其跨度适应能力大、模块化施工、承载能力强、外形美观等优点,近年来受到桥梁建设者的亲睐。依托某钢管混凝土拱桥实际工程,系统地阐述了钢管拱桥静载试验控制断面的选择、测试内容、建模分析,在各项先进检测手段的基础上,从结构强度、刚度及弹性工作性能评价了桥梁工作状况,可为同类工程提供借鉴与参考。

The concrete-filled steel tubular arch bridge has been favored by bridge builders in recent years because of its large capacity to adapt to span,modular construction,strong carrying capacity and beautiful appearance.Based on the actual engineering,the choice of test control section selection,test content and modeling analysis of the static load test of the steel pipe arch bridge have been systematically elaborated.Relying on the advanced detection means,evaluating the bridge work conditions through structural,stiffness and elastic performance has been made,and offering reference for similar projects.
