Analysis of the Impact of Deep Excavation Construction on Adjacent Buildings
Analyze the monitoring data of adjacent buildings at each construction step during the excavation process of the foundation pit.The horizontal and vertical displacement of adjacent buildings increase with the depth of excavation of the foundation pit,and the deformation of the excavation condition is much greater than that of the support condition.The horizontal displacement of the top of the support structure increases with the depth of excavation of the foundation pit,and the displacement of the support structure is much greater than that of adjacent buildings.The support measures effectively limit the displacement of the top of the pit.The deep horizontal displacement under each construction step shows a"bulge shaped"pattern of first increasing and then decreasing with the increase of excavation depth.
