Abstract:

GDEM software was used to analyze the mechanical properties of parallel layered jointed rock masses from different angles, and explore the influence of the change of the angle between the joint angle and the loading direction on the failure mode of the specimen, the parallel layered joint model was established by using different interlayer rock materials commonly in engineering. Through three loading methods, such as static load uniaxial compression, biaxial compression and pure shear, failure forms of such rock mass model at different inclined angles, the stress-strain relationship in the loading process and the variation trend of peak load were analyzed. This study found that the mechanical properties and peak strength of the parallel-level jointed rock mass were directly related to the joint inclination angle. It was found by simulation that the parallel-level jointed rock mass obvious elastic-brittle mechanics under three loading conditions.

Key words: joints, discrete element method, failure mode, mechanical properties, anisotropy
