Abstract

The deformation modulus of a rock mass is among the parameters that can best represent the mechanical behavior of a rock mass. To study the effect of joint roughness on deformation modulus of rock masses, several numerical tests are conducted in this article.The following conclusions can be drawn from the results. (a) the value of JRC(joint roughness coefficient) can affect the deformation modulus; (b) when JRC is less than eleven, the deformation modulus increases with the increase of JRC, and decreases with the decrease of JRC when JRC is greater than eleven; and (c) when JRC is equal to zero (flat joints), the deformation modulus is smaller than others.
