摘　　要：近年来,以机场为中心的综合交通枢纽在交通体系中日益崛起并发挥越来越重要的作用。为提高设计质量,减少振动影响和噪声污染,在有高铁或地铁从地下穿行通过的机场交通枢纽进行车致振动数值模拟分析和现场振动测试工作,显得尤为重要。对高铁列车通过青岛胶东国际机场时,航站楼中心区、GTC及E指廊的结构振动响应进行现场实测,根据各区域振动控制点的实测结果,对振动加速度响应和位移响应的极值情况、时程分布、频谱特性进行统计分析,并给出实测振动结果与有限元仿真计算结果对比。结果表明,现场实测振动量级与有限元仿真计算结果峰值相近,且分布规律一致,验证了仿真计算结果在数值上满足工程要求,车致振动响应的有限元模拟计算方法是适用的。对青岛胶东国际机场高铁列车过站时的振动响应进行现场实测,并与数值仿真结果进行对比分析,验证了设计阶段车致振动模拟结果的正确性。研究成果对其他机场枢纽工程有一定参考价值,尤其是在实测测点布置、工况选择、舒适度评价、数据处理以及对比分析等方面。In recent years,comprehensive transportation hubs centered around airports have emerged and played an increasingly important role in the transportation system.In order to improve design quality,reduce vibration impact and noise pollution,it is particularly important to conduct numerical simulation analysis and on-site vibration testing of vehicle induced vibration at airport transportation hubs where high-speed trains or subways pass through underground.This article conducts on-site measurement of the structural vibration response of the central area of the terminal building,GTC,and E corridor,when a high-speed train passes through Qingdao Jiaodong International Airport.Based on the measured results of vibration control points in each area,statistical analysis is conducted on the extreme values,time history distribution,and spectral characteristics of vibration acceleration response and displacement response.A comparison between the measured vibration results and finite element simulation calculation results is provided.The results indicate that the measured vibration magnitude on site is similar to the peak value of the finite element simulation calculation results,and their distribution pattern is consistent.This verifies that the simulation calculation results meet the engineering requirements in numerical terms,and the finite element simulation calculation method for vehicle induced vibration response is applicable.This article conducts on-site measurement of the vibration response of high-speed trains passing through stations at Qingdao Jiaodong International Airport,and compares it with numerical simulation results to verify the correctness of the simulation results of vehicle induced vibration during the design phase.The research results have certain reference value for other airport hub projects,especially in terms of actual measurement point layout,working condition selection,comfort evaluation,data processing,and comparative analysis.
