摘　　要：本文探讨了凯威特型网壳局部双层形式的构成原则、几何特点 ,给出了五种典型的局部双层网壳形式 ,并对这些结构的几何非线性受力特征、经济指标等进行了深入的分析 ,并与对应的单层和双层网壳作了比较。根据分析结果 。Kiewitt dome is one of the reticulated structures used most extensively in engineering field, and its partial double layer forms is also promising in practice. The construction phiolosophy, geometry configurition nature are investigated herein, and five classical partial double layer Kiewitt domes are introduced firstly. Compared with the single layer and double layer Kiewitt dome used most commonly, geometrical nonlinear analysis have been carried out comprehensively for these K6-6 domes, and economical performance also evaluated in detail. The findings exhibit some practical conclusion from a series of numerical results. [
