Review of critical state theory based constitutive models for bio-cemented granular soils
This paper critically examines some of the proposed constitutive models for granular soils based on the Critical State Theory (CST) framework and their evolution into a cemented soil model. Understanding the behaviour of biocemented soils has been an active area of research over the past two decades. Progress has been made in developing constitutive frameworks to capture their behaviour. One of the popular approaches to model cemented soil behaviour has been to modify the existing CST frameworks for granular soils. Most of these models are highly complex and require a large number of parameters, making them challenging to implement for practical purposes. Various aspects of CST-based models for cemented soil are explored, including assumptions involved, challenges associated, and limitations of the models along with possible pathways forward.
