Research on deep foundation pit excavation based on numerical simulation
Journal of Physics: Conference Series, 2021 Abstract The safety of deep foundation pit excavation has always been an important topic of urban construction safety. The traditional method is to control the construction safety by monitoring and adjusting the construction process, but the timeliness of monitoring makes it limited in the control of construction safety.
