摘　　要：四川国际网球中心会议中心为六层混凝土框架,部分钢结构的工程。因建筑功能要求,结构设计同时包括长度8.4m 的大悬挑梁,两跨跨度分别为16.8m 的等跨框架,主跨跨度为25.2m 的多跨框架梁,以及外挑长度为8.4m 的混凝土悬臂桁架。这几种不同的结构形式均采用了预应力技术,多种预应力结构形式的应用在同一工程中,具有一定的典型意义。介绍了设计的计算过程和构造处理措施,以及施工过程控制要求等。给出的预应力筋线型布置确定过程,及梁裂缝宽度复核方法等,可为今后类似工程的设计提供参考。The conference centre in Sichuan International Tennis Centre is a six-floor concrete frame structure. To satisfy the demands of architecture, prestressed concrete technical ways were adopted in the different parts of the structure,such as in a 8.4 m-long cantilever beam,in a frame with two equal 16.8 m spans,in a frame with multiple spans which the main span is 25.2 m, and in a concrete truss with a 8.4 m-long cantilever. The design procedure and techonic measures were introduced in this paper. Construction control requirements were also discussed. Shape determination of prestressed bars and crack controlling methods of beams were proposed, which can be used in other similar projects.
