摘　　要：随着我国高速铁路的快速发展,高铁站房建设体量庞大,在高铁站房高架层行驶汽车吊并进行构件吊装作业是常见情况,且难度较大。结合广深港高铁虎门站站房改扩建项目作业需求,提出了一种适用于此类工程的临时加固方式,通过组合支撑架将竖向荷载部分传递至下层,给出了基于影响线的计算方法。采用该方法对虎门站高架层组合支撑架进行了设计,并对楼板、主次梁、支撑架等进行了计算,给出了满足各作业工况要求的临时加固方案。With the rapid development of China's high-speed railway,the construction volume of high-speed railway stations is huge.It is common and difficult to drive truck crane and lifting components on the elevated floor.In combination with the operation requirements of the Guangzhou-Shenzhen-Hong Kong High-speed Railway Humen Station Renovation and Expansion project,a temporary strengthening method was proposed,which transferred part of the vertical load to the lower layer by composite shoring scaffold.And the calculation method of based on influence line was put forward.Using this method,the composite shoring scaffold of Humen station was designed,the bearing capacity of the slabs,primary and secondary beams and shoring scaffold are calculated.A temporary strengthening scheme that can meet the requirements of various operating conditions was provided.
