    Abstract
  • Undisturbed loess has significant water sensitivity characteristics. To explore the influence of moisture content change on the microstructure of undisturbed loess, scanning electron microscopy tests of undisturbed loess under multiple moisture content conditions were carried out, and the microscopic characteristics of loess was qualitatively analyzed. The SEM images were binarized using IPP6.0 software to quantitatively describe the pore area, pore diameter, pore morphology, and pore angle distribution of undisturbed loess. The Pearson correlation analysis method was used to analyze the correlation between the moisture content and microstructure indicators of undisturbed loess. The results show that changes in moisture content significantly affect the particle morphology and pore distribution characteristics of loess, manifested as an increase in total pore area, large pore area, average pore size, roundness and convexity, and moisture content with increasing moisture content, while the probability entropy of pores decreases with increasing moisture content.
