| Description | Rock ultrasonic wave velocity and static deformation were measured simultaneously under triaxial loading to investigate the difference and correlation of rock static/dynamic elastic parameters. The results show that rock dynamic Young's modulus is higher than the static one. The correlation of static/dynamic Young's moduli is good. The ratio of static/dynamic Young's modulus is about 0.6. The static and dynamic Poisson' s ratios show some extent of positive dependence but the correlation is more discrete. There is also a difference of static/dynamic Biot's coefficients. The static one is higher than the dynamic one. They are all decrease with confining pressure. The inherent cause of static/dynamic difference is the crack-like pores and the pore fluid in rocks. The external cause is the strain amplitude and its frequency difference under static. And dynamic loading Book Name: Frontiers of Rock Mechanics and Sustainable Development in the 21st Century |
