摘要
针对高速列车行驶的上空挂篮施工存在的安全隐患难题,采用了防护棚架的设计方案,成功地分离了列车与上跨施工的界面,形成了一个全封闭的施工空间。设计中重点考虑了高速列车通过瞬间产生的气动压力和气动吸力对棚架产生的影响,对各种工况条件下各结构受力状态进行了稳定性验算。
Aimed at the hidden danger of cradle construction over the high-speed train,the design of protective scaffolding successfully separated the train and the construction space,forming a fully enclosed construction space.The influence of aerodynamic pressure and suction on the scaffolding was mainly considered and the stress state stability under a variety of working conditions was checked.
