Deformation Response and Safety Evaluation of Buildings Affected by Subway-Station Construction

Based on the sand and pebble stratum in Beijing area, this paper studies interaction between deep-foundation-pit excavation for subway stations surrounding buildings using an orthogonal test. Moreover, it considers relative position relationship how foundation pit is set up as well different design schemes pits buildings. Results show that horizontal distance s building stiffness of itself have a clear impact differential settlement δij deflection Δ, degree deformation near corner complex. Simultaneously, based numerical simulation results, characteristics under relationships with are analyzed. Finally, by establishing among comprehensive index Dj, environmental safety evaluation Sj, scheme grade Lj, multiangle method affected foundation-pit construction formed, which can provide reference research similar projects.
