EXPERIMENTAL STUDY ON SEEPAGE PROPERTY OF ARTIFICIAL SPECIMEN SUBJECTED TO HYDRO-MECHANICAL COUPLING
The stress-strain-permeability behaviors of artificial specimen with different porosity-ratio, have been investigated by servo-controlled MTS 815 rock test system. Influence of porosity-ratio, porosity, seepage on rigidity,peak strength of artificial specimen have been systematically studied by comparing experimental results. It is shown that the relationship of mix-ratio, porosity and permeability, loss equation of hydraulic pressure and porosity on rigidity,peak strength of artificial specimen, provides reference to describe the relationship of porosity, permeability and peak strength. experiment result shown that prominent influence of coarse -grained and macro-pore on porosity and initial permeability, loss influence of water on rigidity,peak strength is boost up evidently when porosity incremental.
