Abstract
Soils in geotechnical engineering are in different mechanical and environmental conditions. What is very important in evaluating unsaturated soils is the study of environmental processes that occur in the soil. Due to the fact that soils are exposed to different climatic conditions in different seasons, its temperature and matrix suction are variable. Also, the study of soil stiffness behavior in dynamic conditions is one of its important parts. Therefore, in this paper, an attempt is made to provide a semi-experimental model for evaluating the maximum shear modulus of unsaturated soils under different temperatures and mechanical conditions, using Thermo-Hydro- Mechanical principles and various laboratory results. Laboratory results are used to validate the proposed model.
