摘要：
Swelling and shrinkage due to moisture-change is one of the expansive soil's 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.
