Deformation Analysis of Adjacent Metro during Deep Pit Excavation
At space compacted, pipeline-intensive, buildings and underground structures adjacent places, environmental deformation is sensitive to deep pit excavation, so deformation as well as slope stability is the control factors for safety. With FEM and automatic remote monitoring, the deformation of adjacent metro in operation was analyzed during the deep pit excavation; acquired results showed deformation caused by pit construction met the requirements of metro tunnel structure less than 4mm.
