Abstract
With the increasing developmental scale of urban underground space, the main contradiction of the urban underground space development has gradually turned from the stability of the foundation pit to the deformation control of the environment around the foundation pit. The underground space development surrounding a complex environment may easily lead to uneven surface subsidence and building cracking, resulting in great economic losses. Therefore, the environmental effect of various excavation foundation pits and environmental effect control technology must be systematically studied. This study introduces and reviews the application of statistical, numerical simulation, and model test methods in the study of the environmental effects caused by excavation foundation pits. This study also summarizes the advantages and disadvantages of each research method, introduces the existing environmental control technology and application cases, summarizes the research results on the environment effect of the underground space development, and proposes some suggestions for future research in this field.
