Abstract: The 2022 Beijing Olympic Winter Games has driven the rapid development of ice and snow sports and venuefacilities in China,Shougang Snowboarding Platform is the first permanent platform built in a city in the world. Accordingto the characteristics of the track curve of big air and aerials freestyle,the possibility of track conversion and variousconversion methods were studied;a regular tetrahedral module and regular tetrahedral connection node were invented,anda modular track conversion mode for Shougang Snowboarding Platform was proposed;through the construction of ShougangSnowboarding Platform demonstration project,the modular conversion and sharing of big air and aerials freestylecompetitions have been realized for the first time,greatly reducing the cost of building two tracks. The modular trackconversion technology complies with the basic principles of standardization and industrialization. It has the characteristics ofeasy installation,strong adaptability,safety,reliability and easy storage. It is also consistent with the developmentdirection of current industrialization of the construction industry,and has the value of continuing to expand research anddevelop,promote and apply to more scenes.
