南昌西站综合交通枢纽环境振动试验分析

Analysis of the Vibration Environment at Nanchang West Railway Integrated Transport Hub

现代大型综合交通枢纽综合了多种交通工具,实现了航空、高铁、普铁、轨道交通、公交和磁悬浮列车等多种交通方式的零换乘或短距离换乘。站房结构中包含高架桥梁、隧道和大跨度空间等复杂结构体系。由复杂结构形式而引发的环境振动,往往对人和精密仪器的使用造成极大的伤害。对南昌西站综合交通枢纽环境振动实测分析的结果表明,振动响应满足环境测评标准和舒适度要求。

Modern large-scale integrated transport hub integrates a variety of transportation to achieve the goal of＂zero change or short-distance transfer＂between air transport,highspeed railway,general railway,urban rail transit,bus and Maglev trains. Station hall structure contains complex architectures like viaduct,tunnel and large-span space,very sensible to a number of environmental vibration problems,which often cause direct harm to passengers and precision instruments.Through field measurement and analysis, the vibration response of Nanchang West Railway Integrated Transport Hub is confirmed to meet the requirements of environmental assessment standard and comfort.
