Risk Identification and Assessment during the Excavation of the Deep Foundation Pit
Advances in Materials Science and Engineering, 2021 This study presents a new model for identifying and evaluating high‐risk factors in foundation pit excavation. The model combines the fuzzy decision‐making trial and the evaluation laboratory (FDEMATEL), the entropy weight method, and the multiattributive border approximation area comparison (MABAC) method.

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.
