ABSTRACT
The hyperbolic model is one of the most popular constitutive models currently being used. It has been applied successfully to solve many practical problems. Kondner 1 was one of the first to propose the use of hyperbolic functions to model the stress-strain behaviour of soils. Duncan and his co-workers expanded the concept and put it into practical use.2 6
This chapter is a review of the hyperbolic model and its application in the analysis of lateral earth pressure problems. The following two questions have been addressed:
(1) can the hyperbolic model predict the deformations for stress paths encountered in the lateral earth pressure problems and
(2) how accurately can the model predict the stress-strain behaviour?
