摘　　要：以大连梭鱼湾足球场为背景,为选择经济、合理的屋盖结构形式,对双层正交轮辐式索结构方案、上层斜交轮辐式索结构方案和双层斜交轮辐式索结构方案进行了对比分析,结果表明,上层斜交轮辐式索结构体系具有较好的经济性和受力性能,可作为大连梭鱼湾足球场屋盖所采用的结构体系。为进一步研究上层斜交轮辐式索结构屋盖张拉施工方案的可行性,设计了缩尺比为1∶20的试验模型,并开展张拉试验,同时采用非线性有限单元法模拟了张拉全过程。结果表明:张拉试验能够准确模拟实际结构的张拉施工过程;张拉过程稳定可控,地面拼装、整体张拉提升的施工方案可行;试验采用的主动张拉索的牵引长度可供实际施工参考。To select the economical and rational structural form for Dalian Suoyuwan Football Stadium,comparative analysis of three schemes was conducted:the double-layer orthogonal wheel-spoke cable structure,the upper-layer crossed wheel-spoke cable structure,and the double-layer crossed wheel-spoke cable structure.The results reveal that the upper-layer crossed wheel-spoke cable structure demonstrates better economical and mechanical advantages,which makes it the final structural system adopted for Dalian Suoyuwan Football Stadium.To investigate the feasibility of the tensioning construction scheme for the upper-layer crossed wheel-spoke cable structure,a 1∶20 scaled experimental model was designed and fabricated.The tensioning experiment was performed,and the tensioning process was further analyzed using the nonlinear finite element method.The results indicate that the experiment can accurately simulate the actual tensioning process,the construction scheme established based on ground assembly and overall lifting is feasible because of the stable and controllable process,and the traction lengths of active cables for experiment can serve as valuable references for practical construction.
