摘要
西昌铁路分局体育活动中心屋盖采用了“四加三卸”加载顺序的多次预应力钢穹网壳新型空间结构。设计时确定了预加应力体系结构的方案，配置了合理的预加力值，制定了可行的张拉工艺。实践证明该结构是一种高效、经济、安全、新颖的大跨空间承重结构体系，值得进一步研究推广。
The roof of a sports centre uses a new type mesh dome space structure which is prestressed several times in the loading turns of “four loading and three unloading.”During the design stage, the plan of prestressed structure is determined,reasonable of pre force is arranged and also the tensile arts is given. Application proves that the structure is an effective, economic, safe and novel large span bearing structural system.
