这是鸟巢官网上的简介，看看合用不：
Located at the southern part of the Olympic Green in Beijing, the National Stadium is the main stadium of the 29th Olympiad in 2008. Occupying an area of 21 hectares, it has a floor space of 258,000 square meters. Its seating capacity amounts to 91,000, including 11,000 temporary seats.
The venue will host the opening and closing ceremonies of the Beijing Olympic Games and Paralympic Games, the track and field competitions, and the football finals. After the Olympics, the stadium will become a large-scale sports and entertainment facility for the residents of Beijing -- an architectural landmark and Olympic legacy.
The main body of the National Stadium has a design life of 100 years. Its fire resistance capability is first-rate, and it can withstand an eight-magnitude earthquake. The water-resistance capability of its underground project is also first-rate.
The main body of the National Stadium is a colossal saddle-shaped elliptic steel structure weighing 42,000 tons. It is 333 meters long from north to south, 294 meters wide from east to west, and 69 meters tall.
The main body"s elements support each other and converge into a grid formation, just like a bird"s nest with interlocking branches and twigs. Being a seven-story shear wall system, the stadium"s stand has a concrete framework. The upper part of the stand and the stadium"s steel structure are separated from each other, but both are based on a joint footing. The roof of the National Stadium is covered by a double-layer membrane structure, with a transparent ETFE membrane fixed on the upper part of the roofing structure and a translucent PTFE membrane fixed on its lower part. A PTFE acoustic ceiling is attached to the side walls of the inner ring.
The construction of the National Stadium followed the PPP mode (Private + Public + Partnership ), and it is co-owned by the Beijing State-Owned Assets Management Co. Ltd (BSAM), who shares 58 percent of the total assets, and the China International Trust and Investment (CITIC) Consortium, who holds the rest of the assets.
Composed of BSAM and CITIC, the National Stadium Co. is responsible for financing, construction, operation and management of the project. CITIC has a post-Games licensed operation right for 30 years.
The National Stadium is a complex structure, posing great difficulties for its designers and constructors.
1. Large and heavy steel parts
The fracture surface of the largest truss column -- the major load-bearing component of the roof structure -- measures 25m x 20m, with a height of 67m. The maximum weight of a single column is 500 tons. The main truss is 12m tall. The maximum span between and through the two columns amounts to 145.577+112.788m, and the maximum span between the two trusses stands at 102.39m. Each truss column is of great bulk and weight, and so are the main trusses.
2. Complex nodal joints
Because the structural elements in the project are box-typed, many elements intersect spatially among the steel parts. Besides, the complex nature of secondary structures has resulted in the diversity of nodal joints of the main structures, requiring accurate and sophisticated manufacturing and installation.
3. Tight schedule
In addition to the huge workload, the allotted construction period is short. Having started on December 24, 2003, the project is expected to be completed by the end of 2007, with the inauguration time scheduled for March 2008. Therefore many operations have to be conducted on a limited terrain, causing a very tense situation.
4. The hoisting work extended across the winter and spring, so the workers have had to defy both rainy and cold conditions in the winter to continue their work.
The workers have overcome tremendous engineering and technical challenges in the process of construction:
1. Difficult work arrangement
They need to do very detailed research of operations and follow meticulous arrangements to complete various kinds of work within a limited workspace.
2. Difficult hoisting of steel parts
To facilitate the assembly of the steel parts, the workers have to use a prone position to assemble the truss columns, which requires a turnover process before they are hoisted. The choice of the hoist points and lug hooks pose great difficulties in the face of bulky and cumbersome steel parts, and the change of pulling stress from three directions must be taken into consideration. The workers need to meticulously rectify angles and positions of the box-typed sectional parts to ensure accurate abutment during the hoisting process.
3. Difficult stabilizing process
They also have to fight the heavy wind load and keep the stability of the steel parts by following a strict working order and use lateral stability measures including the use of anchoring method and wind-holding ropes.
4. Difficult welding
The welders not only face a huge work volume, but also have to work on both the thin steel sheets and thick steel slabs, on high-strength and cast steel elements, and take downward, vertical or overhead positions while welding. They face temperature changes, steel deformation and intensive labor. They need to work above ground, in winter rain and under windy conditions.
5. Difficult installation
The workers face difficulties in ensuring accurate installation as the steel parts and the related gigs and fixtures can be deformed easily under their own dead weight and the change of temperatures. The workers must take pre-installation measures to rectify and relieve the errors that might occur in the process of installation.

Beijing National Stadium (Bird"s Nest/Olympic Stadium)
The Beijing National Stadium, also known as the bird"s nest will be the main track and field stadium for the 2008 Summer Olympics and will be host to the Opening and Closing ceremonies. In 2002 Government officials engaged architects worldwide in a design competition. Pritzker Prize-winning architects Herzog & de Meuron collaborated with ArupSport and China Architecture Design & Research Group to win the competition. The stadium will seat as many as 100,000 spectators during the Olympics, but this will be reduced to 80,000 after the games. It has replaced the original intended venue of the Guangdong Olympic Stadium. The stadium is 330 metres long by 220 metres wide, and is 69.2 metres tall. The 250,000 square metre (gross floor area) stadium is to be built with 36 km of unwrapped steel, with a combined weight of 45,000 tonnes. The stadium will cost up to 3.5 billion yuan (422,873,850 USD/ 325,395,593 EUR). The ground was broken in December 2003, and construction started in March 2004, but was halted by the high construction cost in August 2004.
In the new design, the roof of the stadium had been omitted from the design. Experts say that this will make the stadium safer, whilst reducing construction costs. The construction of the Olympic buildings will continue once again in the beginning of 2005.
In depth
The stadium"s appearance is one of synergy, with no distinction made between the facade and the superstructure. The structural elements mutually support each other and converge into a grid-like formation - almost like a bird"s nest with its interwoven twigs. The spatial effect of the stadium is novel and radical, yet simple and of an almost archaic immediacy, thus creating a unique historical landmark for the Olympics of 2008.
The stadium was conceived as a large collective vessel, which makes a distinctive and unmistakable impression both from a distance and when seen from up close. It meets all the functional and technical requirements of an Olympic National Stadium, but without communicating the insistent sameness of technocratic architecture dominated by large spans and digital screens.
Visitors walk through this formation and enter the spacious ambulatory that runs full circle around the stands. From there, one can survey the circulation of the entire area including the stairs that access the three tiers of the stands. Functioning like an arcade or a concourse, the lobby is a covered urban space with restaurants and stores that invite visitors to stroll around. Just as birds stuff the spaces between the woven twigs of their nests with a soft filler, the spaces in the structure of the stadium will be filled with inflated ETFE cushions. Originally, on the roof, the cushions were to be mounted on the outside of the structure to make the roof completely weatherproof, but the roof has been omitted from the design in 2004.
While the rain was to be collected for rainwater recuperation, the sunlight was to filter through the translucent roof, providing the lawn with essential ultraviolet radiation. On the facade, the inflated cushions will be mounted on the inside of the structure where necessary, e.g. to provide wind protection. Since all of the facilities -- restaurants, suites, shops and restrooms -- are all self-contained units, it is possible to do largely without a solid, enclosed facade. This allows for natural ventilation of the stadium, which is the most important aspect of the stadium"s sustainable design.
The sliding roof was an integral part of the stadium structure. When it was to be closed, it would have converted the stadium into a covered arena; however, the sliding roof was eliminated in an effort to cut costs and increase overall safety of the radical new structure.
