为实现乘客“零换乘”的设计思路,深圳城市轻轨4、6号线高架于深圳北站站房结构上,这使得列车引起的振动直接作用于车站建筑物,并影响到站房其他区域而产生振动,进而有可能影响到站房尤其是候车旅客的舒适性及站内附加设施的使用性能。车站结构设计时,将轨道交通车辆与深圳北站站房建筑物建立动力耦合系统进行分析研究,考虑轻轨列车不平顺、单列、双列、4线同时进站制动的各种情况,把制动力时程输入车站站房整体结构计算,从加速度响应角度对深圳北站站房结构在轻轨列车制动力作用下的振动状态进行分析和评价。计算结果表明,最不利运行工况下,高架列车所致站房振动加速度效应满足旅客的舒适性限值要求。
In order to realize the design idea of passenger “zero transfer ”, Shenzhen URBAN RAILWAY line 4,6 is elevated over the Shenzhen North Station building structure, which makes the train induced vibration directly affect the station buildings and affect the station building Other areas and produce vibration, which in turn may affect the station, especially the comfort of waiting passengers and the use of additional facilities within the station. During the design of station structure, the dynamic coupling system between rail transit vehicles and Shenzhen North Station building is analyzed and studied. Considering the various situations of the light-rail trains that are not smooth, single-row, double-row, and 4-wire simultaneous pitching, Dynamic time history is input into the overall structure calculation of station building. From the perspective of acceleration response, the vibration state of Shenzhen North Station building structure under the braking force of light rail train is analyzed and evaluated. The calculation results show that under the most unfavorable operating conditions, the vibration acceleration effect of the station building due to the elevated train satisfies the passenger comfort limit requirements.
