预制装配式技术在冬奥场馆建设中的开发与应用

The Development and Application of Prefabricated Assembly Technology in the Construction of Winter Olympic Venues

预制装配式技术高效、环保,符合2022北京冬奥会“绿色办奥”的理念。本文所述的国家跳台滑雪中心和首钢滑雪大跳台作为示范工程,围绕冬奥场馆预制装配式技术开展研究,建立了竞赛时冬奥场区临时建筑设施标准体系,研发了赛道设施预制装配式建造技术,其研究成果建立了适用于典型冰雪环境的临时设施及赛道建造预制装配式系列技术体系及标准,实现了冬奥场馆的安全建造及可持续运维,为冰雪运动在我国的发展与推广提供了重要支撑。

Prefabricated assembly technology is efficient and environmentally friendly and in line with the concept of"Green Olympics"of the 2022 Beijing Winter Olympics.Taking the National Ski Jumping Centre and Big Air Shougang as demonstration projects,this paper studies the prefabricated assembly technology of Winter Olympic venues,establishes the standard of temporary construction facilities in Winter Olympic venues during the games,and develops the prefabricated construction technology of track facilities.The research results established a series of prefabricated assembly technical systems and standards for temporary facilities and the construction of tracks for typical snow and ice environments,realizing safe construction and sustainable operation for the Winter Olympic venues,and providing important support for the development and promotion of snow and ice sports in China.
