摘要
海口五源河体育场屋盖结构为月牙形索桁架结构体系,外环直径约260m,索结构最高点相对标高为42.8m。结构具有拉索数量多、施工过程结构变形大、张拉力大的特点,故施工难度较大。为了制定行之有效的施工方案,使用有限元软件MIDAS/Gen,对提出的多种施工方法进行了详细的数值模拟分析,最终确定了"地面铺装拉索,整体提升后张拉径向索"的施工方法,在张拉成形过程中将支座设置为可滑状态。实测数据与有限元数值模拟数据吻合较好,验证了仿真计算的准确性,对同类工程具有参考意义。
The roof structure of Haikou Wuyuanhe Stadium belongs to crescent cable truss structural system. The diameter of outer ring is about 260 m, and the relative elevation of the highest point of the cable structure is 42.8 m. The structure has the characteristics of large number of cables, large structural deformation and large tension force in the construction process, so it is difficult to construct. In order to formulate an effective construction plan, the finite element software MIDAS/Gen was used to carry out detailed numerical simulation analysis of various construction methods. Finally, the construction method of "paving cable on the ground, tensioning radial cable after integral lifting" was determined, and the support was set as slippery state in the process of tension forming. The measured data were in good agreement with the finite element simulation data, which verified the accuracy of the simulation calculation and had reference significance for similar projects.
