摘　　要：琼海市体育场钢结构屋盖呈椭圆形平面,长轴为260 m,短轴为218 m,其主体结构为罩棚结构-空间结构体系.为了确保该体育场在全寿命服役期内安全,提出了琼海市体育场屋盖结构的健康监测方案.首先,使用Midas Gen有限元软件对体育场钢结构屋盖典型构件进行了力学分析,得到特定工况下结构的应力分布和位移情况.在力学分析的基础上,从荷载与环境、结构整体及局部响应方面出发,选定了应变、位移、加速度、风向风速等监测项目并进行传感器选型和监测点位的布设.通过该方案,可对体育场钢结构屋盖进行安全预警,及时了解屋盖结构的状况,为体育场正常运营提供可靠保障.The steel structure roof of Qionghai Stadium has an elliptical plane,with a long axis of 260 m and a short axis of 218 m,whose main structure is a canopy structure-space structure system.in the report,in order to ensure the safety of the stadium during the whole service life,the health monitoring program of Qionghai Stadium roof structure was put forward.Midas Gen finite element software was used to perform the mechanical analysis of the typical components of the steel roof of the stadium,and the stress distribution and displacement of the struc-ture under specific working conditions were obtained.Based on the mechanical analysis data,the monitoring items such as strain,displacement,acceleration,wind direction and speed were selected from the load and envi-ronment,the overall and local response of the structure,and the selection of sensors and the layout of monitoring points were carried out.The program can be used for the safety warning of the steel structure roof of the stadium,the condition of the roof structure can be determined in time,and provide the reliable guarantee for the normal operation of the stadium.
