摘　　要：介绍武钢铁路48号线钢梁桥检测试验情况,主要有桥跨竖向横向刚度,桥墩横向刚度,钢梁桥应力及强度试验,钢梁偏心与上拱度测试,并进行实测定量及定性分析。试验结果表明,该钢梁桥各项指标均满足现行荷载运营要求。本试验还为该梁检修及其修程提供理论依据,节省盲目性工程资金投入,确保钢铁运输生产顺行。The present paper introduces the tests on the steel bridge at the No.48 line of the railway in WISCO,primarily including check and test on the vertical and transverse stiffness of the bridge span,the transverse stiffness of pier;stress and strength of the steel bridge and eccentricity and camber of girder as well as quantitative and qualitative analysis on the testing results of those items.Experimental results show that indicators of all items of the steel bridge are completely in conformity with the requirements of current on-load running for the bridge.Through the tests on the bridge very reliable theoretical datum have been achieved for future maintenance and repair of the bridge and thus project spending without plan can be saved and smoothly running of the railway transportation for iron-making and steel-making purpose guaranteed as well.
