Abstract

A three-dimensional numerical modeling combined with in-situ measurements was performed to investigate the deformation behavior of a braced excavation for construction of underground metro station and its influence on the adjacent piles. The computed lateral deformation of the retaining wall agrees well with those of the field monitoring, indicating that it is feasible to use numerical model to predict the deformation of the embedded piles, which can not be acquired at the site. The study reveals that the design and construction countermeasures adopted in this project restrict the deformation of the retaining structures as well as the embedded piles, and ensure the safety of the structures effectively.
