摘　　要：深圳游泳跳水馆主馆屋盖结构采用了一种新颖的大跨度空间结构形式——带斜拉桅杆系统的主次立体桁架结构。本文首先介绍了该屋盖结构的结构布置特点以及结构计算分析要点。结合该屋盖结构的分析,本文特别对目前大跨度屋盖结构分析的两个重要问题——预应力分析方法和风振响应计算进行了讨论。文中归纳了三类等效的拉索预应力空间结构的预应力分析方法,即断索法、初作用法和初内力法。同时采用模态补偿法对该屋盖结构的风振响应进行计算,最终通过一个等效风振系数的形式来反映。根据该屋盖结构的分析结果,本文最后对斜拉桅杆系统拉索张力的预应力效应及合理取值、分支拉索的结构性能、圆钢棒拉索的受力特性等问题进行了讨论。The roof structure of Shenzhen Swimming and Diving Hall is a new type of space structure composed of a main spine truss and four orthogonal trusses with four sets of cable stayed masts. In this paper, the characteristics and some analytical keypoints of the roof structure were put forward first.For the two important issues which were often concerned about in the design of long span structures, the prestress analytical methods and the wind induced vibration response computation were specially discussed. According to the structural analysis, some suggestions about the prestress effect of cable stayed mast system, reasonable prestress magnitude, mechanics properties of filiation tendons and so on are given in the end.
