A hypoplastic model for soft clays incorporating strength anisotropy
Original language description
The paper presents a new hypoplastic model for soft clays accounting for their typical fea-ture - strength anisotropy. The model is based on the latest version of the hypoplastic model for clays (Mašín 2014), enhanced by the anisotropic shape of the state boundary surface. It has been shown that by skewing of the ASBS the model predicts different ultimate strength of the material. Additionally, the tensor L is made bi-linear in D to more realistically predict the stress path. The new model has been evaluated by simulating la-boratory experiments on soft marine clays (Corral & Whittle 2010) involved in the Nicoll highway collapse in Singapore, a prominent case of geotechnical failure. Furthermore, other typical soft clays were used for cali-bration, such as Bangkok clay. The significant advantage of the model lies in its easy calibration using only simple undrained triaxial and oedometer tests.
