| 摘 要： | 通过对动载试验实测值与基于跨长、频率两类规范计算值比较,以及对相关影响因素分析,表明多跨先简支后连续钢筋混凝土空心板桥梁冲击系数,与频率相关,但不遵守规范规定的单调函数规律,满足一定的域值,与动荷载速度相关,满足高阶多项式函数关系,与桥梁孔位基本无关。

| Abstract: | By comparing the moving load test values and calculated values based on span and frequency norms, and through an analysis of related factors, it is indicated that the Shocking Coefficient of Reinforced Concrete Hollow Slab Bridge Constructed by Simple Support and Continuous Support is related to frequency but does not follow the monotonic function specified by the norm, conforming to certain field value, with no relation with the velocity of the moving load, conforming to high-order polynomial and with no relation to beam position. |

| Keywords: | shock coefficient frequency moving load velocity continuous beam bridge |
