Abstract The coupled shear-flow behavior of rock joints is an important issue in rock mechanics. A number of coupled shear-flow tests were carried out under different normal loading conditions. By means of visualization system，flow images during shear process were taken and processed. Using the finite element method，with a special algorithm by treating the contact areas as zero-aperture elements，numerical simulations of fluid flow in joints were conducted. Numerical simulations providea good agreement with the flow rate obtained from tests，revealing that the flow paths and aperture distributions in a joint change remarkably with shear displacements，loading conditions and joint surface roughness.
