N2 - Applications of several enhanced bounding surface models for analyzing a deep excavation-induced ground movements in an urban area are presented in this paper. Such applications require knowledge of bounding surface theory within the concept of conventional constitutive modeling. Incorporations of the bounding surface models and a commercial finite element code provide a useful approach to evaluate the performance of deep excavations associated with soft soils. With respect to the evaluations, it was found that (i) agreement between finite element simulations and field observations in terms of lateral soil movements and nearby surface settlements was satisfactory; (ii) in most stages of the excavation the simulations obtained using the isotropic version of the enhanced bounding surface model were slightly improper than for the case of the anisotropic versions of the model; (iii) utilization of the advanced soil models (enhanced bounding surface models) can lead to a more realistic prediction of excavation-induced ground movements; however, careful consideration of detailed processes relating to constructions should be desired.
