| 摘 要： | 针对铁路提速后部分预应力混凝土简支T梁桥横向振 动幅值偏大这一现象,以24m和32m铁路预应力混凝土简支 T梁为研究对象,较系统地分析了横隔板厚度和横隔板开裂对 单跨简支梁横向动力性能的影响规律,这对提高设计质量和对 现有桥梁进行正确的状态评估与加固具有一定的参考价值。

| Abstract: | After railway speed increase, majority of simple PC T beam bridges’ transverse vibration amplitude exceed allowance value. Taking simple supported PC T beam (which span is 24m and 32m respectively) as study models, a systematical research on the influence law of cross slab on the dynamic performance of single span simple supported PC T beam was conducted. It has significant reference value for the improvement of railway design, state evaluation and reinforcement of bridge. |

| Keywords: | railway bridge PC T beam cross slab transverse vibration |
