  • A large number of vertical macropores are developed in loess. The vectorization of vertical macropores in loess is the basis and difficulty of the study of fabric constitutive relations of loess. Based on industrial CT scanning and beads chain filling method, this paper develops a set of software for vectorization and characterization of loess macropores. The specific functions of the software implementation are:1)CT scan reconstruction of the 3D model of loess macropores; 2)automatic filling and pore separation of the loess ball chain; 3)Automatic statistics of the distribution characteristics of single pores; 4)Calculation of fabric tensor and fabric tensor coefficient of loess macropores model based on Stereology technology. The results show that the beads chain filling method and the developed software can vectorize the fabric characteristics of loess pores. The software lays a foundation for the fabric description of loess.
