Abstract

Abstract: The NHRI constitutive model is one of the elasticplastic models, which utilizes the advantages of DuncanChang model and Cambridge model. The model has multiple yield surfaces and improves the disadvantage existed in the DuncanChang and the Cambridge model, in which they cannot simulate the stress path under a decreasing confining pressure. This paper presents the model determination of saturated silty soils by using the triaxial tests.

Key words: The NHRI Constitutive Model, Triaxial Tests, Saturated Silt
