钢管混凝土拱桥的荷载试验研究

Research on Load Test of Concrete-filled Steel Tubes Arch Bridge

钢管混凝土拱桥结构造型美观、跨度大,是城市桥梁常用的一种特殊结构形式。为了延长桥梁的使用寿命,保证桥梁结构运营安全,桥梁特殊检测至关重要。结合工程实例,介绍了荷载试验检测的内容及过程,检测结果可以判定桥梁结构的整体刚度、强度以及动力特性响应是否在正常范围内,可为桥梁日常养护或有针对性地维修加固提供基础数据。

The concrete-filled steel tubes arch bridge is a kind of special structural form commonly used in urban bridges because of its beautiful shape and large span. In order to prolong the service life of the bridge and ensure the safety of the bridge structure operation,the special detection of the bridge is very important. Combined with the engineering project,the detection content and process of the load test are introduced. The detection results can be used to determine whether the overall stiffness,strength and response of dynamic property of the bridge structure are within the normal range,which can provide the basic data for the daily maintenance or targeted maintenance and reinforcement of the bridge.
