摘　　要：从结构特征上看,安顺市体育中心体育场钢罩棚的单榀结构形式属于大跨度悬挑平面管桁结构,在施工过程中首先在地面上对构件进行组装,然后采用起吊装置在空中进一步组合,采用逐步成型的工艺,钢罩棚在施工状态下与及竣工状态下的受力几乎是完全不同的。笔者通过建模的方式,对整个施工过程进行模拟,从而了解结构受力变化以及在此过程中发生的形变。分析结果表明,施工过程对大型复杂结构的影响显著,模拟其施工过程可有效提高工程的安全性,合理指导施工,降低工程事故风险。In view of the structure characteristics, the form of a single-bay structure of the steel roof of Anshun Stadium is a long-span cantilevered flat tube truss structure, the structure was assembled into segments, hoisted the internal and external ring segment, high-altitude docked together and gradually formed, and the steel roof in construction state and completion state of stress is almost entirely different. The whole construction process was simulated by means of modeling so as to understand the change of structure stress and deformation of the struc- ture. Analysis results show that ： the process of construction has a significant impact on the structure , to simulate the construction process can effectively improve the security of the project, reasonably guide the construction and reduce project risk of accidents.
