摘　　要：吉林省速滑馆屋面为桅杆式钢结构预应力索拱体系,钢结构吊装采取分段吊装并集合高空散装,穿插进行索结构挂索施工。然后进行钢索张拉,测试索应力,根据测试数据最后进行整体索张拉调整。Jilin Speed Skating Gymnasium roof adopts mast type steel structure prestressed cable arch system. The steel structure is lifted in segments and then the segments are assembled in the air. Meanwhile, cable structure construction is carried out. Thereafter, the steel cable is tensioned and cable stress is tested. At last, the whole cable tensioning is adjusted according to the test data.
