Research on excavation and reverse construction technology for deep and large vertical shafts

Abstract

Reverse construction method is an unconventional construction method, generally used in special situations such as deep foundations, complex geology, and high groundwater levels. Underground structures are constructed using reverse construction method, which can reduce costs, shorten construction periods, reduce the impact on the surrounding environment, and ensure construction safety. It is an effective method for constructing high-rise basement or underground structures. However, the theoretical analysis of underground structures started relatively late, especially in terms of construction theory, which is not yet very complete. Therefore, it is necessary to conduct in-depth and detailed research on the construction process.
