ABSTRACT

ABSTRACT: Both laboratory and field tests show that the seismic amplitude tomography (SAT) owns higher capability in sensing joint properties and distribution than the available velocity tomography Experimental comparisons between amplitude and velocity are illustrated concerning joint parameters such as aperture, joint roughness, joint frequency, and dilation under various normal and shear stresses. Then, two kinds of mapping by SVT and SAT which were obtained from the investigation of the dam site are discussed in terms of joint orientation and distribution.
