摘要
近年来,桁式组合拱桥病害成因分析中,其活载横向偏载效应是否存在一直是工程技术人员和研究者重点研究的问题之一。结合桁式组合拱桥5座桥梁的荷载试验,利用桥梁静力荷载试验有关偏载加载工况测试数据,对桁式组合拱桥的偏载系数规律、特点进行分析和总结,相关结果可供类似桥梁设计参考。
In recent years in analysis of causes of diseases in combined truss arch bridges, existence of transverse bias effect of live load has been always one of problems focused on research by engineering technicians and researchers. In combination with load test of 5 combined truss arch bridges, this paper analyzes and concludes the laws and features of load bias factor of combined truss arch bridges by means of test data in static load test of bridges concerning bias loading conditions, and the associated results can provide a reference for design of similar bridges.
