In the overall spatial layout, the center broke the static relationship of the traditional sports center, fully demonstrated the beauty of speed, strength and coordination of sports, and made the overall effect reflect the characteristic context of Yueyang River, mountains and lakes, becoming a symbol and symbol of the city. The center connects two exhibition halls and the northern business district in series with a one-stop pedestrian landscape system, which ensures the integrity of the pedestrian system and the continuity of the central landscape system, weaves the main buildings in the north and south of the base into an organic whole, and forms the overall planning and layout structure of "four-point-five areas on both sides of one belt", echoing Yueyang's regional characteristics, natural landscape and spiritual connotation of sports power and beauty.
Five veins converge, and the dragon is auspicious. The sports center has two halls in turn. The building stands on the mountain, with ups and downs in shape, echoing from beginning to end and broken pens. The stadium shines like a dragon ball and becomes a highlight of the center. The stadium is like a dragon head, the torch platform is like a dragon horn pointing to the sky, and the towering hotel is better than the dragon tail. The whole pulse and the pulse of the mountains and rivers complement each other, and the dragon gets aura because of the mountains and rivers, swallowing the dragon ball. Outdoor basketball courts, tennis courts, gateball courts and other sports venues are connected into an organic whole with four theme sports squares, such as fitness culture square, gymnasium front square, roller skating square and tourism commercial culture square, through an integrated walking system, which runs through the stadium area in a tortuous way, showing the noumenon character of the sports center and deducing the core spirit of sports power and beauty. In particular, the fitness cultural square on the south side of the stadium shows the citizens the rich cultural system of the city's sports center through landscape elements such as water, sculpture, inscriptions, calligraphy and greening, which creates conditions for Yueyang citizens to provide high-quality public venues.
Stadium:
The stadium is located at the southern end of the sports center. The urban green belt with a width of 100 meters in the south is connected with the landscape avenue of Baling East Road. The main road in the sports center echoes the reserved mountain, gymnasium and swimming pool in the north, Meizi North Road in the west and Datang Road across the National Fitness Square in the east. The total construction area is 3 1099.6㎡ and the total number of seats is 22,603. The main building of the stadium has three floors, with the first floor as the main functional building. The second floor is the audience platform. The third floor is the mezzanine of the box and the press building. The outline of the stadium stands is a four-center circle, and the stands are covered with a complete steel canopy similar to the plane shape of the stands. There are all track and field events and an international standard size lawn football field.
Because of its functional noumenon, stadium modeling is beneficial to athletes' competition and audience's watching, which naturally produces an overall modeling with high middle and low north and south. Simple and elegant, exaggerated warping is better than the vividness and softness of Yueyang Tower, which has far-reaching implications and is intriguing. The two roofs are separated, high in the west and low in the east, and the tail end of the east roof is thrown to the west, echoing the west roof. A torch platform grows in the gap between the two roofs, like a mast, like a dragon boat about to sail, and like a dragon, full of movement and ready to go, which explains the overall design concept of "Longteng" from another angle ... Four stepped platforms are introduced to connect the audience outside the building to solve and assist the evacuation problem of the upper audience. Its trend is similar to that of the roof, just like a dragon galloping and jumping. The dynamic modeling is imaginative, achieving the perfect balance of function, technology, culture and art. The overall modeling of the stadium is inspired by Yueyang's unique regional customs and traditional context, and is deeply branded with Yueyang culture. It is the link between history and future, Yueyang and the world, symbol and reality, reflecting Yueyang's cultural spirit and infinite vitality since ancient times.
Gym:
The comprehensive gymnasium is located in the middle of the sports center base, and is connected with the stadium and swimming pool in the north-south direction. The main entrance faces Datang Road, the secondary road of Dongcheng, and a crowd gathering square is set on the east side of the gymnasium. The total construction area of the gymnasium is 2 1952.6 square meters, of which the aboveground construction area is 20,484 square meters, the underground construction area is 594.6 square meters, and the platform construction area between the stadium and the gymnasium is 874 square meters. The total number of seats is 8 136 (excluding disabled seats 16), including 5475 fixed seats and 266 movable seats1.
Gymnasium adapts to the multi-functional needs of different sports competitions, and the infield size is considered according to the handball field, taking into account the usual training. It can meet the requirements of indoor competitive competitions such as basketball, volleyball, handball, table tennis, judo, taekwondo, gymnastics, etc., and can meet the needs of gatherings and cultural performances through changes in seats and venues. Usually used for mass fitness, it can provide 4 basketball courts or 20 badminton courts. As an exhibition, it can provide 2 16 standard quasi-booths, which greatly improves the flexibility and utilization rate of the venue. The competition venue should be paved with imported advanced movable wooden floors that meet the requirements of NBA competition standards, and the venue can be temporarily changed when other multi-functional competitions are held.
The image design of the gymnasium highlights the design concept of "Dragon Ball presents ruins", adopts a reasonable structural form, and forms a clear, powerful and distinctive architectural image through the shape changes of the roof and wall. The exterior is a spiral integral shape, and the folded plate roof adopts a steel tube portal frame structure with radial layout and triangular cross section, and adopts new energy-saving and environmental-friendly building materials, which embodies the characteristics of modern architecture such as light, fast and efficient.
Swimming pool:
The swimming pool is located at the north end of the sports center, close to the commercial residential area on the north side of the base, and echoes the reserved mountains, gymnasiums and stadiums. The total floor area above ground is 13048.07m2, and the total number of seats is 1278. 50m and 25m standard swimming pools 1, 50m outdoor swimming pools, diving pool 1 and children's swimming pools 1.
The main body of the swimming pool is three floors, and the first floor is the main functional room; The second floor is smoothly connected with the stadium through a 6-meter-wide evacuation platform, which also facilitates the evacuation of the swimming pool after the game and the connection of the second-phase development building; The third floor is the fitness building. The connection between swimming pool and gymnasium mainly provides services for outdoor swimming pool, and the underground part is related equipment room.
The swimming pool and the "floating" landscape platform are interwoven into an organic whole, and the pure roof and transparent facade make the external form of the building more concise and flexible through the comparison of materials. The virtual building surface reduces the heaviness of the building structure, overlooking the swimming pool, like a white cloud lingering in the mountains. The reserved mountain, the extended roof and the three-dimensional traffic platform are isomorphic to form a multi-level spatial gradient, which reflects the overlapping feeling of the integration of architecture and natural environment. Look at the swimming pool carefully, like a passionate wave, which implies the meaning of dragon boat culture. A bird's eye view of the swimming pool is like a fallen leaf falling quietly between the quiet mountains and rivers.
