摘　　要：国家速滑馆采用马鞍形双曲屋面造型,选用单层双向正交索网作为主体屋面的结构支撑体系。索网是典型的柔性结构,其上的屋面构造的柔性变形能力是研究的重点。依据研究成果,设计首先采用由若干个相互独立的单元板块平铺支撑在索网上,形成柔性屋面结构基层,其次采用高分子卷材及隐形变形缝构造形成柔性防水面层,从而研发一种能适应索网变形的柔性屋面构造。The saddle-shaped hyperbolic roof is adopted in the National Speed Skating Oval,and the single-layer two-way orthogonal cable net is selected as the structural support system for the main roof.Cable net is a typical flexible structure,and the flexible deformation ability of roof structure on it is the focus of the research According to the research results,firstly,the flexible roof structure base is formed by several independent unit plates which are supported on the cable net;secondly,the flexible waterproof surface is formed by polymer membrane and invisible deformation joint structure,so as to develop a flexible roof structure which can adapt to the cable net deformation.
