Analysis on ROI Characteristics in CT Images of Q2 Loess under Freezing Temperature
Freeze-thaw action is one of causes to loess disaster. Loess structure and mechanical properties are quite different due to its structural model, unsaturation and salt content, which make loess freezing much complex. The samples from the site are set with different moisture content and lowered their temperature to 0°C, -10°C and -20°C respectively, and then the microscopic damage propagation and damage structural variation in the internal loess have been studied under the different freezing temperatures through CT scanning experimental technique. With zoning methods and zoning statistic frequency, the process of damage evolution has been analyzed, which provides specific guideline for researches on geotechnical engineering in loess region.
