The ice jade ring aerial trail “ice jade ring” starts from the concept of “Olympic giant ring complex” proposed by the preliminary team from Switzerland, and connects key buildings such as the national ski jumping center, the national biathlon center, the national cross-country ski center, the mountain broadcasting center and the technical official hotel through the elevated trail.
It is vividly called “ice jade ring”.
The main building function is cross-country ski resort, including cross-country ski track, competition management center, spectator stand and other functions.
The venue is planned to be located in a long and narrow valley.
They are the best experience space for the cultural logo of the Winter Olympics and the landscape of the valley.
It is divided into two half rings from the East and the west, and the west half ring is erected from the ground, The inner ring is 1.9 kilometers long, 15 ~ 24 meters wide, 7 meters high and the highest climb is 38 meters; On bingyuhuan is the front yard area, which is used as the audience channel, and on the ground is the backyard area, which is used as the working area of event operation guarantee; This is the first time in the history of the Winter Olympic Games to distinguish the front and rear courtyards through three-dimensional transportation, with an intensive land area of about 40000 square meters.
The platform section is vividly called “xueruyi” because it matches the S-shaped curve of the traditional Chinese auspicious ornament “Ruyi”, It is the first ski jumping site in China that meets international standards, with the largest amount of work and the highest construction difficulty.
87% of the supporting functional space of Yunding venue is provided through temporary facilities, with a total temporary construction area of 26000 square meters.
In the design of external materials and colors, in order to avoid the strong reflection and ice cold feeling of the common white steel plate finish, the European pine plate finish and dark temporary building frame are selected, and the material reflectivity is reduced from more than 70% to less than 50%, reducing the overall environmental brightness..
According to the standard of star hotels, the hotel refines the internal space and facilities, so as to provide space quality support for the sustainable operation of the hotel after the game.
The contour of each floor is consistent with the contour of the natural terrain.
The altitude rises from 1617m in the entrance area to 2105m at the top of the snow track, with an overall drop of 488m.
The hotel follows the natural mountain trend and expands horizontally.
Most of the prefabricated temporary buildings used in the venue are mainly container houses with flexible loading and unloading, supplemented by tents and other structures.
The flat field in the future can be used as a football field after the game, and can also hold the opening ceremony, concert and press conference of large-scale games.
Renewable materials and environment-friendly engineering technology shall be used as much as possible in the construction process, and the surrounding mountain vegetation shall be protected and restored in time.
The shape design of the circular elevated walkway echoes Chinese culture.

The site selection of “xueruyi” makes full use of the natural landform and has two tracks with a drop of 136.2 meters and 114.7 meters respectively.
Through the overhead and long-span structure on the ground floor, the mountain broadcasting center raises the public space and studio viewpoint on the second and third floors to form a continuous open vision, with “snow Ruyi”, “ice jade ring” and mountains as the background of the TV broadcasting room.
At the same time, the design optimizes the user’s visual experience and the effect of live broadcast during the game by controlling the parameters such as the angle of studio window, glass refractive index and reflection coefficient.
Among them, the architectural design and Research Institute of Tsinghua University led the planning and architectural design of the whole and all venues in Zhangjiakou competition area and Shougang venues in Beijing competition area.
The center adopts the principle of minimum intervention in the natural environment to minimize the scale of permanent buildings, integrate the functions during the games, use temporary facilities to meet the needs during the Olympic Games, restore the natural ecology after the games, and minimize the impact and damage to the environment; The cross-country track integrates multiple tracks, tries to expose most of the cross-country tracks to the view of the audience, increases the viewing of the game, and is unique in the design of the Olympic cross-country track.
National cross-country skiing center the national cross-country skiing center covers an area of 106.55 hectares, with a permanent construction area of 5707 square meters and a temporary facility area of 17400 square meters.
Mountain Broadcasting Center & Technical Officer Hotel technical officer Hotel and mountain broadcasting center are the supporting facilities of ancient poplar group.
The drop and shape of the valley are highly consistent with the needs of the race.

Obstacle chasing, parallel great gyration, slope obstacle skills, U-shaped venue skills Air skills and snow skills 6 tracks, and Zhangjiakou Mountain News Center.
Looking from the jumping platform, athletes can vaguely see the ruins of the great wall of the Ming Dynasty in the distance.
The 2022 Beijing Winter Olympic Games and winter Paralympic Games officially kicked off yesterday.

They are divided into two buildings a and B.
Beijing and Zhangjiakou are both host cities, which are divided into Zhangjiakou competition area, Beijing competition area and Yanqing competition area.
After the competition, bingyuhuan is open to the public as a public leisure and fitness venue, and promotes the sustainable development of the Olympic movement through mass activities such as the Olympic ring race and cultural and art exhibitions.

they are located on the inner slope of the overhead trail “bingyuhuan”, facing the national ski jumping center “xueruyi” across the mountain and valley.
It is covered with snow in winter and naturally embedded in the surrounding mountains.
The eastern half ring road is a hiking trail, which is 1.1km long, 2 ~ 4m wide and has a maximum climb of 115m.
Different from the previous jumping platform design at home and abroad, “xueruyi” has set up the peak space at the upper part of the athletes’ departure area for the first time.
