摘要
通过对京通线银镇沟桥的现场振动测试 ,得到该桥的横向振动特性 ,给出桥上列车轮轨作用力的典型时程曲线和列车的脱轨系数及轮重减载率 ,为进一步研究矩形桥墩的横向振动提供实测数据。
A field vibration test was conducted for Yinzhengou Bridge on JingTong Railway Line,resulting in the lateral vibration characteristics of the bridge,and a typical time-history curve of the wheel-rail action force,derailment coefficient of trains,and the rate of wheel load reduction,providing measured data for further study on the lateral vibration of rectangular-shaped bridge piers.
