Influences of Abnormal Climates on Engineering Characteristics of Expansive Soil
Expansive soil is a kind of high plastic clay which is more sensitive to changes of climatic and hydrogeologic conditions, and it has the character of swelling when watering and shrinking when drying out. Such repeated fluctuations from dry to wet induce irreversible deformation, which will make the shear strength and internal friction of soil drop sharply and cause slope fracture. In recent years, abnormal climatic changes worldwide make foundation stability of expansive soil face severe test. Atmospheric influence depth can supply design basis for slope fracture of expansive soil. But in the situation of abnormal climates, the depth will exceed original design criterion and hazard engineering accidents will happen. Therefore, It has great importance in engineering application of studying influences of abnormal climates to engineering characteristics of expansive soil.
