Abstract: This study aims to explore the creep damage evolution law and crack propagation characteristics of fractured rock masses with different dip angles. Using the RDL series electronic creep relaxation testing machine and acoustic emission （AE） monitoring system， uniaxial creep tests were conducted on specimens with inclinations of 0°， 30°， 60°， and 90°. The creep mechanical properties and acoustic emission characteristics of crack specimens with different inclination angles were analyzed. The resear... More
