Abstract
Artificial Ground Freezing techniques eliminate the need for structural supports during the course of an excavation, as frozen ground is solid and waterproof. At present, it is adopted as an effective way to deal with various construction ground control challenges such as the mitigation of seepage infiltration into tunnels and shaft excavations; or ground strengthening for excavation. In-depth knowledge of the frozen soil characteristics through experiments and the development of suitable constitutive models that suit the geological conditions of our country are necessary to predict the strength and behaviour of the frozen soils. This paper presents a review on the various constitutive models used in soil analysis. Authors hope that this article will help to develop better understanding of frozen soil properties and emphasize the need for accurate constitutive models incorporating the characteristics of soils in our country.
