IOP Conference Series: Earth and Environmental Science, 2020 Abstract Pit-in-pit is common in foundation pit-engineering practice. Pit-in-pit excavation disturbs the stress field in the passive zone of the foundation pit, which induces the loss of soil resistance in the passive zone and adversely affects the safety of the foundation pit.

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.
