When the foundation pit has one of the following characteristics, it needs to be supported :(1) the buildings around the foundation pit are close to the excavation edge of the foundation pit, and the stratum is relatively weak; (2) The surrounding buildings are sensitive to excavation and disturbance; (3) When the excavation depth of the foundation pit is greater than 3 meters, and the vertical retaining structure resisters the deformation caused by the load outside the foundation pit and damages the adjacent buildings and structures, it is necessary to set supports to control the deformation of the foundation pit during the excavation process, so as to ensure the safety of the foundation pit and surrounding environment.
