The Analysis on Monitoring Data and Finite Element Simulation of the Deep Foundation Pit in Tianjin

摘要

Through the analysis on monitoring data of the deep foundation pit in Tianjin, it was observed cd that the lateral deformation of the retaining wall at the coiner was smaller than the deformation in the middle. Based on the analysis of the results drawn from finite element simulation of the excavation process and the monitoring data, appropriate supporting structure stiffness parameters values used in Plaxis and Qimingxing are recommended for designing deep foundation pits in soft soil area.
