EXPERIMENTAL STUDY ON DEFORMATIONAL MODULUS OF FRIABLE ROCK DURING COMPACTION
松散岩块压实变形模量的试验研究

Through the experimental research on the compaction of friable rock block, the relationship among deformation modulus, axial stress and strain were obtained. The result of this experiment reveals that the tangential modulus is exponential with axial stress, and varies with rock block size and rock property. The secant modulus is linear with axial stress. Both the tangential modulus and secant modulus are exponential with axial strain. The conclusion of this research is valuable to analysis of deformation mechanism of friable rock compaction.
