Abstract

Abstract

The dynamic compressive strength characteristics and macroscopic failure modes of layered phyllite are carried out by the Split Hopkinson Pressure Bar. The micromorphology of fracture surface was obtained by 3D laser instrument, and the fractal geometry was introduced to quantitatively describe the roughness of fracture surface. Based on the fracture mechanism observed by SEM, the dynamic failure mechanism of layered rock with different bedding angles is analyzed. The results indicate that the weak bedding plane has a great influence on the dynamic compressive strength of layered rock. The fractal dimension of layered phyllite changes in U-shape with the increase of bedding angle. The influence of bedding plane on the failure characteristics of layered rocks is examined according to strength and crack propagation. For specimens with bedding angle of 0°, the failure strength is controlled by rock matrix, but the weak bedding plane still has a large impact on the distribution and trend of cracks in rock failure. For specimens with bedding angle of 22.5°, strength and direction of cracks are controlled by both the rock matrix and weak bedding plane. For specimens with bedding dip angle ranging from 45° to 67.5°, strength and direction of cracks are controlled by weak bedding plane. For the bedding angle of 90°, the dynamic compressive strength of the specimen is affected by the rock matrix, and longitudinal macro-cracks are formed early on the weak plane of the bedding, which results in that the cracks are greatly affected by the bedding plane.
