摘　　要：滁州奥体中心体育场为开口式大悬挑预应力屋盖体系,最大悬挑跨度39.2 m。结合钢结构施工部署,通过对施工全过程数值模拟进行预应力专项方案的编制,通过一系列同步张拉技术、抗风斜撑后装技术等保证结构成型后的内力、变形符合设计初始态要求。根据施工模拟计算可知所有胎架在张拉完成后均脱胎,对判断预应力导入结构体系有明显的判断作用,并结合施工过程结构健康监测技术,对张拉全过程进行变形、索力和应力监测,将施工实测值与理论计算值作对比,保证结构成型后的安全性和可靠性。The Chuzhou Olympic Sports Center Stadium is an open large cantilever prestressed roof system with a maximum cantilever span of 39.2m.Combined with the construction deployment of the steel structure,through the numerical simulation of the whole construction process,the special pre-stress plan is prepared,and a series of synchronous tensioning technology,wind-resistant diagonal brace post-installation technology,etc.,ensure that the internal force and deformation of the structure after forming meet the requirements of the initial state of the design.According to the construction simulation calculation,it can be known that all the tire frames are born after the completion of the tension,which has an obvious role in judging the introduction of the prestress into the structural system,and combined with the structural health monitoring technology during the construction process,the deformation,cable force and stress of the entire tensioning process are carried out.Monitoring,comparing the actual construction value with the theoretical calculation value to ensure the safety and reliability of the structure after it is formed.
