Gu Ailing said in an interview after winning the championship that the Shougang big jump platform is the best venue he has ever skated. "This venue, first of all, the degree of it is very good. And under normal circumstances, this kind of snow-made field is very hard and easy to freeze. But it's not that hard here. Gu Ailing said with a smile that she did not know how such an ideal venue was achieved, but it felt very good to compete in the Shougang big jump. How to build the big jump platform? Why does it feel so good? Zhang Li, chief designer of the Shougang Ski Jump and dean of the School of Architecture of Tsinghua University, gave the answer.
The slope design of the ski slope is more precise
The evaluation of athletes, coaches and referees is the most authoritative judgment of the stadium in the state of competition use. Because of this, at the beginning of the design, the Shougang Big Jump platform specially interviewed a large number of athletes to understand the specific needs of professionals. "What they think is the best big jump, how to design it better, what they care about, we all have to absorb." Zhang Li said.
"The degree of the venue construction is very good, it feels very good." Why did Gu Ailing have such an experience? Zhang Li said that for athletes, the most important slope perceived is the slope of the slope.
"All the preparation before the take-off is on the slopes, which determines how far all the preparations can go. The slope of the slope of the shougang big jump is 37.8 degrees, which is calculated by experts from the International Snow Federation. Zhang Li said that compared with some previous jumping platforms, the permanent jumping platform built in Shougang Park has more accurate slope control, wider ski slopes and larger drops, so it has better acceleration preparation and experience for athletes.
Industrial legacy gives athletes a different kind of excitement
The environment and multi-element fusion of the Shougang big jump platform form a strong "force".
"When people perceive space, they are affected by the perception of all the surrounding scenery." Zhang Li analyzed that the Shougang big jumping platform faces Qunming Lake, and the overall environment of the industrial heritage around the jumping platform has a different stimulation of the athletes' psychology. "As soon as you exit the ramp-up elevator, you will be greeted by a variety of industrial heritage in the surrounding area, and the ski trail in front of you will also lead to an industrial heritage environment. Helping to slide downhill, it will be a very exciting experience for them. ”
The soft viscosity of the snow surface is large and helps to play
Gu Ailing said that "the venue is comfortable and not hard, not very icy", Zhang Li also gave an analytical answer. He believes that the main reason behind it is the difference in temperature and site structure.
"Some of the competitions that Gu Ailing has participated in before, many times in the mountains, are windy and relatively cold. However, the Shougang big jump platform is in the urban area, and the temperature is relatively high, which is different. Zhang Li said that especially in the morning, the competition is arranged, and the solar energy shines on the snow surface with a large inclination angle, "the snow surface is soft and sticky, and the athletes will like it." ”
The second factor is that the Shougang Grand Jump is itself a permanent building structure, more stable than the temporary structure. Zhang Li said that the Shougang big jump platform can be imagined as a bridge. When competing, the area on the "bridge" is "stable and elastic from the perception of vibration, and it will not appear so hard." ”
