- Abstract:
- In view of the failure characteristies of layered roek mass, a series of physical experiments were car.ried out in this paper. The disruplion and strength fealures of the layered rock in the case of uniaxial eompres.sive are diseussed to explore the diseipline of the dip angle and interlayer changes elleet on strength and breakage of roek mass. The test results show that the roek mass destruetion modes are mainly rock destruetion fosmall dip angle (0 <45°), interlaminar shear failure with the dip angle inereases (45°≤θ<75°)and layerdireetly damage with loeal spliting failure for the dip angle of 90°. Abaqus soltware was used for the numeriealsimulation on the above model tests. The theoretieal analysis and numerieal simulation show that the compres.sive strength of rock is first deereased and then inereased with the “["-shaped disribution. The ealeulationresults are consistent with the resulls of laboralory test.
