摘　　要：西安曲江电竞馆比赛馆屋盖为多层大跨焊接球网架结构体系,下部施工条件极为复杂。为解决大面积弱承载力地下室顶板、大范围看台、施工对结构位型和内力分布的扰动等问题,通过合理划分施工分区和优选施工工艺的手段,采用基于有限元的MIDAS和盈建科软件对施工过程和结构静力进行分析,对施工方案的可行性进行了全面分析和介绍,为类似工程施工关键技术选择提供了参考依据。The roof of Qujiang E-sports Competition Stadium in Xi'an adopts a multilayer long-span welded ball grid structure with extremely complicated construction conditions below.In order to address such problems as large-area basement roof with weak bearing capacity,large-area spectators stand,and construction disturbance to structural positions and the distribution of internal force,construction partitions are divided reasonably,appropriate construction technology is prioritized,and the construction process and structural static force are analyzed by using finite element-based MIDAS and YJK Building Software,so that comprehensive analysis and introduction on the feasibility of the construction scheme have been achieved,thereby providing a reference for the selection of key construction technology for similar projects.
