摘要:
以大胜关长江大桥吊杆为研究对象,基于健康监测系统对高速列车通过时钢桁拱桥吊杆的振动速度进行长期监测,通过对振动速度积分的方法来获得大胜关大桥吊杆动位移幅值的长期变化规律.分析结果表明:吊杆横向动位移幅值显著大于纵向动位移幅值,并且两者都可以采用广义极值分布函数描述其概率统计特性;吊杆纵向动位移幅值与主梁横向动位移幅值存在明显的相关性;吊杆横向振动主要由高速列车局部风效应引起,并且横向动位移幅值与环境温度存在明显的相关性.因此,吊杆横向振动分析应考虑局部风场和温度的共同作用,吊杆纵向振动分析应考虑与主梁横向振动的耦合作用.
Abstract:
Taking Dashengguan Yangtze River Bridge as the research object, based on the structural health monitoring system, the vibration velocity responses of the hanger were long-termly monitored when the high-speed train passed. Then the long-term variation regularity of dynamic displacement was further obtained through the integration of vibration velocity responses. The analysis results indicate that the dynamic displacement amplitudes of the hanger in the transverse direction are much larger than those in the longitudinal direction, and their probability characteristics can be described by the generalized extreme value distribution function. There is a significant correlation between the dynamic longitudinal displacement amplitudes of the hanger and the transverse dynamic displacement amplitudes of the main girder. The transverse vibration of the hanger is mainly caused by the local wind effect of the high-speed train, and the transverse dynamic displacement amplitudes of the hanger and the ambient temperature have an obvious correlation. Accordingly, the local wind field and the temperature should be taken into consideration in the transverse vibration analysis of the hanger, and the coupling effects of the transverse vibration of the main girder should be considered in the longitudinal vibration analysis of the hanger.
