| 摘 要： | 通过理论计算和现场实测,分别得出红水河铁路斜拉桥在机车通过时的动力响应,并将两种方法得到的结果进行分析和比较。结果表明,红水河铁路斜拉桥在机车荷载作用下的横向动位移幅值介于0.6~1.4 mm之间,动挠度幅值介于17.9~20.2 mm之间。计算结果与实测结果接近,较客观地反映了桥梁结构的动力响应规律。

| Abstract: | The dynamic responses of Hongshui River Railway Cable-Stayed Bridge under traveling of locomotive were obtained respectively by the theoretic calculation and filed measurement and the results of the responses obtained by the calculation and measurement were analyzed and compared.The results indicate that the lateral dynamic displacement values of the Bridge under the action of locomotive load range from 0.6 mm to 1.4 mm while the dynamic deflection values range from 17.9 mm to 20.2 mm.The results of the calculation are close to those of the field measurement and can fairly objectively represent the laws of dynamic responses of the Bridge structure. |
