摘　　要：中国航海博物馆建筑的中央帆体结构基本体系由风帆屋面、单层索网玻璃幕墙以及边侧玻璃幕墙等3部分构成,索网找形是结构施工中重要环节。张拉顺序的不同会产生不同的网格形状,而网格的形状直接影响到玻璃的排布和下料。通过缩尺模型试验来考察张拉方式对索网成形的影响,试验结果和数值分析结果为实际工程中索网的施工提出了方便可行的张拉方案。The basic system of the central sails in the building of China Navigation Museum consists of sail roof, Single-layer cable nets glass curtain walls and side glass curtain walls. The form-finding of cable nets becomes very important for constructing the building because different ways of cable pretension may form different shapes of net meshes which affect the pre-ordering and dimensions of the glasses, rio investigate the influence of cable pretension on form-finding of the nets a reduced scale model was carefully designed to conduct model experiments for different pretension ways. The model experiment and analysis are very helpful to the realizing of the pre-tensioning and construction of the full size cable nets in real project.
