摘要
曲线桥在使用过程中,上部结构易发生横桥向的变位.在车辆移动荷载作用下的振动响应对曲线桥的侧向移动的影响,逐渐引起人们的重视.为保证桥梁的安全使用,选取城市道路中常见的混凝土连续曲线梁作为研究对象,利用数值模拟方法,分析车辆过桥过程中汽车质量对曲线桥侧移的影响,得出曲线桥安全使用的车重范围.
The upper structure of curved bridge tends to vibration response of curved bridge under moving vehicle be subjected to lateral displacement during use. So the effect of loads on the lateral displacement of curved bridge has gradually gained attention. In order to ensure the safe use of the bridge, this paper selects the research object of concrete continuous curved beam which is often used in urban roads to analyze the effect of vehicle weight on lateral displacement of curved bridge when the vehicle is crossing the bridge by using the numerical simulation method, and obtains vehicle weight range for safe use.
