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 ,本文的计算结果是比较满意的 The train bridge system is taken as a whole.According to the theory of random vibration energy, the artificial vibrating train and the measured serpentine traveling trains are used as the transverse excitation sources, and the vibration response of the quasi-high speed train passing through the reinforced concrete continuous beam bridge at different speeds is calculated. Compared with the test results, the calculation results in this paper are quite satisfactory
