The composite color with gray tone is the "background color" of the Olympic Sports Center: the roof panels of all venues are made of imported aluminum, manganese and magnesium alloys, forming a large area of silver-gray layer, gray fair-faced concrete walls, gray ground granite and dark gray asphalt pavement ... Why use gray tone? Because the silver-gray color is close to the background color of Nanjing traditional houses and gray brick bluestone Ming city walls, it is a continuation of Nanjing traditional context, which more prominently shows the culture of the Six Dynasties and the geography of the ancient city, implies the theme of "sports and history" and is also a rich modern beauty.
Many stadiums and gymnasiums in the world have become idle burdens after large-scale sports meetings. The design of the Olympic Sports Center considers how to improve the utilization rate and reduce the high maintenance cost. The Olympic Sports Center Stadium is completely designed according to the concept of the fifth generation international sports complex, that is, to realize "park" on the basis of multi-function. For example, on the 3rd and 5th floors of the main stadium, referring to the commercial operation mode of foreign stadiums, there are 156 VIP boxes, which will be sold publicly after the 10th National Games. The floor of the gym can be opened. By converting four underground reservoirs, it will become an ice-making pool and an ice rink, which can be used at any season of the year. After the floor is closed, it will become a normal venue for sports competitions and cultural performances. Seen from a distance, the swimming pool presents a unique snail shell shape. The main and auxiliary halls of the swimming pool are attached together like two snail shells of different sizes, which symbolizes that the athletes' arms are struggling to paddle in the green pool and go straight to the finish line. The unique design and novel appearance have brought problems to the layout of the interior space. How to achieve the best combination of unique structure and internal use? Entering the museum from the tail of the snail shell, we found that there are four pools in the small snail shell, namely the children's swimming pool and training pool in the leisure area, the swimming pool in the competition area and the diving pool. It makes the best use of resources. People can't help sighing the whimsy of designers and the ingenuity of construction workers.
