However, although the aperture condition of rock joint is important factor, the many researches with this factor have not been performed. In this paper, the effects of which the shear behavior of rock joint is depended on the magnitude of aperture condition are discussed. Especially, the numerical index representing the degree of the aperture condition with rock joints is proposed, and furthermore, we applied this index on the shear strength equation proposed by authors.}, pages = {637--642}, publisher = {土木工学会}, title = {Estimation Method of Aperture Condition with Rock Joint and Its Application for Shear Equation}, year = {1999} }
