摘　　要：深圳大运中心体育馆所采用的结构形式比较新颖,整个结构相当于将其众多的三角形网格,围绕一个曲面(虚构面)折上折下或折左折右,组成一种创新的结构,称作"空间单层折面网格结构"。本文从结构体系的构成入手,分析了该结构的优缺点,提出了结构体系优化的必要性和改进方法,并从结构的受力、刚度、材料用量等多个方面介绍了结构优化的效果。The sturctural form of Shenzhen Dayun Center is relatively new, and the whole structure is composed of numerous triangle grids folding around a curved surface to create a kind of innovational structure which is called as ＂the singlelayer space fold surface grid structure＂. The advantages and disadvantages were analyzed in this paper of the structure from the perspective of structural system＇s constitution, the necessities for the optimization of structural system and the methods of improvement were put forward, and the effect of structural optimization on the internal forces, stiffnesses, and material usage are illustrated.

关 键 词：网格结构 体系构成 优化设计
