Abstract
Super high-rise building is a typical architectural form of urban modernization, and it is also the trend of urban architectural development. This paper reviews the development history of super high-rise buildings in China combined with the engineering practice of representative super high-rise buildings since the 1980s, such as the Shanghai Center, Shanghai Oriental Pearl Tower, Jinmao Tower, Shanghai World Financial Center, Canton Tower, and Shanghai Tower. The development process of the key technologies of super high-rise projects from the aspects of several technologies, such as soft soil pile foundation and foundation pit technology, concrete structure construction technology, integral formwork equipment technology, and steel structure comprehensive installation technology, is also elaborated. At the same time, the Shanghai Tower is selected as a typical case to share the innovative technology of China’s tallest building. Finally, prospects for development of super high-rise construction technology are presented.
Highlights
As a typical architectural form of urban modernization, super high-rise building can effectively realize the architectural function and value increment, which is the trend of urban architectural development
With respect to verticality control of pile foundation, a complete set of construction technologies are developed innovatively, which improves vertical accuracy of pore-forming by more than 50% compared with the national standard. e innovative construction technology of bored piles has served as a reference for subsequent constructors to apply bored piles in super high-rise buildings on soft foundations in China
Technical methods for deformation control of foundation pit earth excavation enclosure on rheological properties of soft soil could be found in Chapter 23, Construction of Foundation Pit Earthwork, in Handbook of Foundation Pit Project [22]. e microdeformation control technology methods of foundation pit projects are listed in Technical Standard for Micro-Deformation Control of Foundation Pit Project (Shanghai Standard) edited by Shanghai Construction Group (SCG) and Tongji Architectural Design. e standard is the first standard in China that boasts of super level quantitative control indicators and explains micro-deformation control in design and construction of foundation pit [23]
Summary
As a typical architectural form of urban modernization, super high-rise building can effectively realize the architectural function and value increment, which is the trend of urban architectural development. Before the 1980s, the world’s high-rise and super high buildings were mainly concentrated in developing countries such as the United States, the United Kingdom, Russia, and Canada. After the 1980s, China gradually moved away from the debate about the construction of high-rise and super high buildings. A large number of high-rise and super high buildings were successively built in large cities such as Shanghai, Beijing, and Guangzhou, among which Shanghai is the most representative. Combined with the engineering practice of super high buildings such as Shanghai Center, Shanghai Oriental Pearl Tower, Jinmao Tower, Shanghai World Financial Center, Canton Tower, and Shanghai Tower, etc., this paper analyzes and discusses the development of key technologies for ultrahigh construction projects in China by systematically summarizing and reviewing the development history and key construction technologies of representative super high buildings
