| Abstract: | The characteristics of compressional wave velocity induced by cracks in rocks are examined experimentally under room temperature and pressure. Some artificial crack models are also studied to investigate the influence of cracks density and relative position in rocks on velocity. The results suggest that the compressional wave velocities are highly crack-dependent and of oleponds on the crack orientation,numbers and types. While not changing the crack orientation,the relative position of cracks in rocks has no influence on velocity |
