摘　　要：将列车桥梁系统视为一整体 .根据随机振动能量理论 ,以列车构架人工蛇行波和实测蛇行波为横向激振源 ,计算了准高速列车以不同的速度通过钢筋混凝土连续梁桥的振动反应 .与测试结果比较 。The train and bridge are considered as a whole system. According to the random vibration energy theory, by taking the artificial hunting curves and the actual measured hunting curves of the train frame as the transverse excitation source, the vibrating responses are calculated when a quasi_high_speed train runs through the reinforced concrete multi_span box girder at different speed, the results of which are found to be in satisfactory with test data.
