摘　　要：西安奥体中心游泳跳水馆是集游泳、跳水、花样游泳、水球比赛、文化休闲活动于一体的多功能体育场馆,底部为钢筋混凝土框架结构,屋面为倒三角立体管桁架结构。介绍游泳跳水馆几个关键部位的设计,通过SAP2000软件模拟的刚度方案对比分析,总结出预制看台板在常规软件中的简化建模方法,提出了预制看台对主体结构长短柱效应影响的调整系数;屋面体系分析中阐述了檩条与立体桁架的共同作用,不需设置纵向稳定桁架;超大跨楼板舒适度控制应采取软件模拟分析与现场实测相结合的方式综合确定;介绍了承办国际赛事的比赛池和跳塔的控制要点等。The swimming and diving hall of Xi’an Olympic Sports Center is a multi-functional stadium integrating swimming,diving,synchronized swimming,water polo competitions,and cultural and leisure activities.The bottom is a reinforced concrete frame structure and the roof is an inverted triangular three-dimensional tube truss structure.Several key parts design of the swimming and diving hall was introduced.Through the comparative analysis of the stiffness schemes simulated by SAP2000 software,the simplified modeling method of the prefabricated grandstand board in the conventional software was summarized,and the adjustment coefficient of the prefabricated grandstand on the effect of the main structure of the long and short columns was proposed.The synergy of purlins and three-dimensional trusses was explained on the roof system analysis,without the need to install longitudinally stable trusses.The comfort control of the super-large-span floor slab should be comprehensively determined by a combination of software simulation analysis and on-site measurement.The control points of the competition pool and the jumping tower for hosting international competitions,etc.were introduced.
