摘　　要： 结合近年来多项预应力拉索网格结构工程的实践 ,以多个各具特色的预应力拉索网格结构工程———山西太旧高速公路标志建筑斜拉网壳和悬挂网架 ,广州越秀山体育场挑棚斜拉网架 ,苏州工业园区游泳馆预应力拉索网架 ,厦门海沧大桥收费站预应力拉索网架 ,嘉善体育馆预应力网架 ,浙江海洋学院体育馆斜拉网架为基础 ,阐述了预应力拉索网格结构在工程中应用的形式、设计思想、索张拉力与垂跨比的关系以及拉索作用方式和效果。 Based on the authors' experience in design and analysis of grid structures with prestessed cables, several practical projects are introduced first. These grid structures include cable-stayed reticulated shell in Jiuguan toll station o f Taijiu express highway, suspended grid structure of Yuexiu Mountain Stadium in Guangzhou, prestressed grid structure of Natatorium in Industry Area of Suzhou, cable-stayed grid structure in toll station of Haicang Bridge in Xiamen, prestr essed reticulated shell of Jiashan Gymnasium and curved face grid structures wit h prestessed cables of Zhejiang Marine College Gymnasium. Then, some important a spects of design and analysis of grid structures are illustrated such as layout and effect of prestressed cables in practical application, method and thinking o f design and analysis, and relation between axial force of cable and span-depth ration.
