摘要
以广州地铁六号线为工程背景,对高架区间的预制节段箱梁进行孔道摩阻测试,总结以往孔道摩阻的试验方法,介绍了本次摩阻试验的方法,分析了孔道摩阻数据,得出实际的摩阻系数和偏差系数,修正桥梁电算的模型,使计算结果更能符合实际,同时也为同类桥梁的设计参数提供参考。
On the 6th line of Guangzhou subway project background,elevated range precast segmental box girder to channel friction test,summed up the previous channel friction test method described in this friction test methods,analysis of the pore friction data,obtained the actual friction factor and bias factor,modified bridge computer models,make the results more realistic,but also the design parameters for the bridge to provide similar information.
