Influence of Deep Foundation Pit Partition Construction on Deformation of Adjacent Subway Structure and Analysis of Protection Countermeasures
Through the analysis of the deformation impact of the adjacent subway structure during the construction of a certain underground civil air defense project foundation pit,it is shown that the excavation of external deep foundation pit earthwork has a significant impact on the deformation of the adjacent subway structure.However,under the excavation principle of"layering and blocking,first supporting and then excavating,and timely sealing",by optimizing the construction plan,the final deformation of the subway structure can be effectively controlled.
