Abstract

Each of the current analytical methods used in rock and soil CT mechanics is “observation”, wasting the precious CT quantitative information. Utilizing the set theory and the measure theory, the concepts of the ? level damage-fracture ratio and the ? level damage-fracture rate, the ?1-?2 level intercepted section ratio and rate, the ? level damage-fracture content are defined based on the CT number, simultaneously furthering to research the relation among the ? level damage-fracture rate, the CT number and the density, the relation among the bulk strain, the density damaged increment and the CT number, the relation among stress, strain and the density damaged increment.
