| Abstract: | The construction technology of the top-down method has gradually got the social recognition with its safe, efficient, economic and environment-friendly characteristics. Combined with an engineering practice, the paper introduces the key techniques of the top-down method for the large deep foundation pit excavation, including the vertical support construction technology, the inverse excavation technology, the top-down installation technology for the formwork, the key connection node technology, the working environment control technology and the informatization monitoring. A set of standardized construction process has been formed in related research, and its relevant experience and data can provide reference for the further development and research of the top-down construction technology. |
