Abstract: This paper provides a review of the constitutive models for unsaturated soil, including the Unsaturated Soil Constitutive Model (BBM model) and its extensions, the water-soil coupling model, and models considering temperature effects. While the introduction briefly outlines representative constitutive relationship models, the focus of this paper lies in the theoretical research and simulation aspects of these models. The development history and theoretical foundations of unsaturated soil constitutive models are extensively discussed in the review, emphasizing their significance in describing the mechanical properties and behaviors of unsaturated soils. Various types of constitutive models are elaborated upon to aid readers in better understanding the complexity of unsaturated soil and simulation methodologies. Furthermore, this paper delves into the applicability and limitations of unsaturated soil constitutive models under different environmental conditions, as well as the prospects of their application in practical engineering problems. Through a comprehensive analysis of relevant research literature and experimental data, the paper showcases the importance and developmental trends of unsaturated soil constitutive models in the field of soil mechanics. By summarizing and discussing these aspects, this paper aims to provide readers with a comprehensive review of unsaturated soil constitutive models, offering insights and inspiration for research and academic discussions in related fields.
