摘　　要：北清路(京新高速~京承高速)快速化改造工程中,新建高架桥需跨越北京地铁8号线。为确保施工期间地铁正常运行及施工人员的顺利作业,采取了搭建移动式安全防护棚结构的方法。本研究以此为研究对象,采用midas GEN建立该防护棚模型,将列车实测振动输入该结构,研究地铁振动对该防护棚结构的影响,确保防护棚在地铁运行情况下的安全。In the rapid transformation project of Beiqing Road(Jingxin expressway~Jingcheng expressway),the new elevated bridge needs to cross Beijing Subway Line 8.To ensure the normal operation of the subway and the smooth operation of construction personnel during the construction period,a method of building a mobile safety protection shed structure was adopted.This study takes this as the research object and uses midas Gen to establish a model of the protective shed.The measured vibration of the train is input into the structure to study the influence of subway vibration on the protective shed structure,ensuring the safety of the protective shed under subway operation.

关 键 词：地铁运行 安全防护棚 数值模拟 振动响应
