| 摘 要： | 分析了桥梁损伤产生的原因,对比了桥梁的不同加固方法.通过对某下行线预应力混凝土简支梁加固后的实验结果分析,以跨中实测横、竖向振幅,振动加速度以及动扰度曲线为依据,研究了在提速列车作用下加固后桥梁自身的动力特性及其动力响应.对加固前后桥梁的动力特性进行了比较.

| Abstract: | The analysis and comparison of the different bridge reinforcement methods was introduced.The institute experiment result of prestressing concrete simply supported beam of XiaoTangHe Bridge,which had been reinforced on the ShuoHuang railway,is analyzed.Based on the lateral and vertical amplitude history,the vibration acceleration and curve of dynamical deflection gained from the experiment,the dynamic characteristics of the reinforced bridge and its response under raised-speed trains were studied.The compari... |
