青岛北站主站房施工仿真计算分析

Construction process simulation of Qingdao North Railway Station

青岛北站主站房为大跨预应力钢结构,结构体系复杂。钢结构施工过程中存在结构体系转换,使得施工过程中的结构受力都与原设计状态存在区别。为保证结构施工过程安全,需要进行仿真分析,得到结构的内力、位移变化数值,用于指导施工。采用MIDAS进行全过程施工仿真分析,验证了施工方案满足设计要求,得到施工控制关键部位,为类似工程提供借鉴。

The main station structure of Qingdao North railway station is a complex large-span prestressed steel structure. The structural system of the steel structure transforms during the construction process, in which the force on the structure is different from that in design. Simulation of construction process was necessary to ensure the safety of construction, in which the obtained internal force and displacement can guide the construction. With the application of MIDAS, simulation of construction process was conducted to verify the construction plan, obtain critical parts of construction control and provide reference for similar projects.
