Abstract

[A three-dimensional numerical simulation based on FLAC3D was carried out to investigate the deformation characteristics of a braced excavation with top-down method in typical Shanghai soft soil deposits. The lateral displacement of the retaining wall, the ground surface settlement, and the subsoil movement outside the excavation were studied in detail. The predicted ground surface settlement curves agree well with the empirical ones, therefore, the reliability of the calculated results is verified, which can provide a useful guidance for engineers in design and analysis of similar excavation projects with top-down method.]
