【Abstract】 An equivalent model analyzing elastic constants of jointed rock masses is presented by the method of material mechanics. The analytical formulas for estimating basic elastic constants of persistent jointed rock masses are derived. The corresponding common procedures are written and the effects of one or more sets of joints as well as the orientational angles of joints on the rock masses properties are analyzed based on the presented model. The equivalent elastic matrix and material constants predicated have a good agreement with the results by using the numerical method with joint elements. It is a simple and practical method for predicating the equivalent elastic parameters of jointed rock masses.更多还原
