| 摘要: |
| 为在2022年冬奥会期间将国家游泳中心泳池场地改造为冰壶场地,结合临时场地的新型制冰方式,提出了一种全装配式的冰壶场地及支承结构体系的构造作法.对此装配式冰场进行了现场试验测试和有限元受力性能分析,研究了装配式冰场的自振频率和振型特点,分析了冰场在使用荷载作用下的整体变形和各组件的应力水平,探讨了极端荷载作用下冰面受力、变形及开裂等关键问题.研究表明,所提装配式冰场方案具有较大刚度和承载力,能够满足冬奥会冰壶比赛对冰面的要求；此类冰场宜使用轻型浇冰车作业,大型浇冰车轮压引起的弯矩和剪力作用下冰面存在开裂的可能. |

| Abstract: |
| To transform the swimming pool of the National Aquatics Center into a curling field for the 2022 Winter Olympics, a construction method of a fully assembled curling field with supporting structure was proposed in consideration of a new ice-making method. Based on the results of field test and finite element analysis conducted on the assembled ice rink, the characteristics of the natural frequencies and corresponding mode shapes of the assembled ice rink were studied. The overall deformation and the stress level of each component of the ice rink under service loads were analyzed, and the stress, deformation, and cracking in ice layer under extreme loads were discussed emphatically. The research shows that the proposed assembled ice rink had greater stiffness and loading capacity, which can meet the requirements of curling games in Winter Olympics. This kind of ice rink should be operated by a light ice resurfacing machine, since ice cracking is likely to be generated under bending and shearing actions of wheel load of large ice resurfacing machines. |
