Influences of Deep Foundation Pit Excavation on the Stability of Adjacent Ancient Buildings
The excavation of deep foundation pits has a significant impact on the stability of adjacent buildings. On the basis of a deep foundation pit project in Xi’an, China, the deformation of a diaphragm wall and the settlement and deformation of an adjacent ancient building with and without MJS (Metro Jet System) pile reinforcement were studied through ...

Risk Identification and Assessment during the Excavation of the Deep Foundation Pit
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.
