The stadium is the largest single building in Dalian Sports Center. It is a five-story single-story large space structure. According to the functional layout, it is divided into athlete area, competition management area, news media area, VIP area and audience area. There are two training grounds on the east and west sides outside the stadium, covering an area of 60,000 square meters.
The steel structure of the main roof of the stadium consists of 68 planar cantilever trusses and 6 hoop trusses. The total steel consumption of the main steel structure is more than 5,300 tons, and the development area of membrane structure is 60,000 square meters. In addition, there is a huge stand, which can accommodate 665,438+0,000 spectators. During the construction, in order to ensure the quality and progress of the project, the sports center adopts the modular and industrialized construction form of factory prefabrication and on-site assembly for the stadium stands and steel structures. This construction concept and technology have been fully affirmed by the leaders of Liaoning Provincial Construction Committee, and promoted as advanced experience in the whole province.
Like the Water Cube in Beijing, the stadium adopts ETFE membrane structure, and the competition venue has advanced seepage control system, which will not accumulate water even if it rains cats and dogs. Gymnasium is the soul of the whole complex of Dalian Sports Center, covering an area of 95,000 square meters, with a building area of 83,000 square meters and 6,543,800 seats. The design and construction of the gymnasium is based on the requirements of hosting the Olympic Games. It can host basketball, volleyball, table tennis, badminton, handball, gymnastics, boxing, indoor football, ice sports and NBA events. At the same time, it also has the function of holding large-scale entertainment activities. In addition to15,000 fixed seats, there are 3,000 retractable seats in the venue, with box seats, broadcast room, warm-up area for athletes, underground parking lot and dining area.
The gymnasium adopts a "suspended dome" structural system. The highest point of the roof is 45 meters, the horizontal span is about 1 16 meters, the vertical span is about 145.4 meters, and the plane is irregular and oval. It is one of the largest span suspen-dome structural projects in the world. According to statistics, there are more than 30,000 basic components in the steel structure project of gymnasium roof. In order to meet the architectural requirements of the century-old project, all welds in this project are Grade I welds; After calculation, the structural members of this project are composed of about 6,543,800 connecting plates and nearly 20,000 linear meters of primary welds.
It is the environmental protection feature of the gymnasium to adopt a variety of new processes and technologies to achieve maximum energy saving and emission reduction. For example, in the design of air conditioning system, advanced heating and refrigeration systems such as exhaust air total heat recovery, layered air conditioning, seat air supply and secondary air return, low-temperature floor radiation heating are adopted, which greatly reduces the energy consumption of air conditioning during the operation of the venue; In addition, the vertical edge locking system and intelligent snow melting system used in the roof of the gymnasium can solve the drainage problem of the roof of the large gymnasium well.
The gymnasium can accommodate10.8 million people, and it is one of the gymnasiums with the largest number of visitors in China. During the construction of the gymnasium, in order to cope with the wind disaster, Dalian Sports Center made a rigorous simulation experiment at Harbin Institute of Technology and made a model of 1: 10. In order to prevent the damage of sudden typhoon, aluminum veneer technology is also added; At the same time, if the extreme freezing weather causes the city power grid to be paralyzed, the generator located in the basement of the gymnasium will automatically generate electricity in a very short time to meet the operation requirements of the gymnasium.
If an ice hockey game is staged in the gymnasium, it will meet the requirements of NBA game after 36 hours. It sounds strange and can be staged in sports management. In the process of design and construction, the gymnasium was endowed with the ability of "thirty-six changes". The huge four-story "bucket screen" hanging in the center of the competition venue can be adjusted up and down to meet the needs of the audience to enjoy wonderful events and performances in all directions without dead ends. The swimming pool covers an area of 50,000 square meters, with a building area of 39,000 square meters and 4,200 seats. According to the functional layout, the swimming pool is divided into competition area, competition management area, athletes and team officials area, news media area, referee area, audience area, logistics office service area, equipment and auxiliary area.
The swimming pool is equipped with a standard swimming pool with 50m long 10 lane, a standard diving pool with 50m long and 8m lanes, and a warm-up pool for training. The swimming pool can meet the requirements of the Olympic Games and world-class individual events, and can hold swimming, synchronized swimming, diving, water polo and other events.
The overall building and facilities of the swimming pool are comparable to Beijing's "Water Cube", and the technical level of its electrified intelligent equipment is also in a leading position in China. The underwater monitoring of swimming pool can observe, record and immediately play back the underwater movements of athletes during competition and training; The competition pool is also equipped with humanized facilities such as mobile terminal wall and electric water entry equipment specially designed for disabled athletes. Diving pool has also set up air wave-making and water wave-making systems, as well as internationally advanced safety air cushion systems to prevent divers from being accidentally injured during training.
The water treatment system of swimming pool is equipped with conventional physical and chemical filtration and disinfection system to purify the water, and the most advanced biological purification system in the world is used to treat the water harmlessly, and the environmental protection level has reached international standards. June 20 13, the 12th National Games tennis match was held in the Tennis Center of Dalian Sports Center. This is the first high-standard competition held by the Tennis Center.
The tennis court covers an area of 6,543,800 square meters, with a total construction area of 44,000 square meters, including a tennis final venue with a capacity of 6,543,800+people, an indoor tennis training venue with three venues, two semi-final venues with a capacity of 6,543,800+people, eight preliminaries and six training venues, which can host the world's top tennis events all day.
The function configuration of the tennis center can not only meet the requirements of professional sports teams and athletes for indoor training in bad weather, but also consider the various requirements of national fitness and informal indoor tennis competitions. The baseball field covers an area of 40,000 square meters with a building area of 1.900 square meters, which can accommodate 30 1.5 spectators and can host international professional baseball events. When a softball game is held, the baseball field can be transformed into a standard softball field.
The baseball field is a comprehensive baseball (softball) field with small volume, full functions and strong practicability, which integrates competition and training. The Media Center covers an area of 22,000 square meters with a building area of 78,000 square meters. It can not only meet the functional requirements of the news media in the sports center to broadcast and report all sports events, but also has a powerful reception function as a five-star hotel with 400 rooms.
