Study on Initial Cracking of Expansive Soil and FEM Simulation

Article Preview

Abstract:

Swelling and shrinkage due to moisture-change is one of the expansive soils characteristics, which is similar to the behavior of most materials under thermal effect. The stress is defined as moisture-change stress and is adopted to analyze swell-shrinkage deformation based on the elasticity mechanics theory. A FEM program is established which is used to calculate the stress caused by moisture-change considering the defect of theoretical calculation. The stress via FEM program can be accordance with the actual characteristics and the moisture-change is more applied extensively.
