EVALUATION OF CLAY CONSTITUTIVE MODELS FOR ANALYSIS …

WebFive soil models, i.e., the modified Cam clay model, the hardening soil model, the hardening soil small strain model, the Mohr-Coulomb (φ = 0) and the undrained soft clay model, are selected for evaluation. The TNEC excavation case history, which was with well-documented monitoring data and soil properties, is used for this purpose. Webloading surfaces model (SSLSM) and the kinematic hardening structure model (KHSM). Various boundary-value problems are then analysed. The results for the two models are compared with each other, as well with those from standard Cam-clay models. Accuracy and eﬃciency of the scheme used for the complex models are also investigated. 食品マーク
