An Experimental and Numerical Study on Cracking Behavior of Brittle Sandstone Containing Two Non-coplanar Fissures Under Uniaxial Compression

Abstract: To understand the fracture mechanism in all kinds of rock engineering, it is important to investigate the fracture evolution behavior of pre-fissured rock. In this research, we conducted uniaxial compression experiments to evaluate the influence of ligament angle on the strength, deformability, and fracture coalescence behavior of rectangular prismatic specimens (80 9 160 9 30 mm) of brittle sandstone containing two non-coplanar fissures. The experimental results show that the peak strength of sandstone contai… Show more

“…In the BPM, the intact rock is represented by an assembly of separate particles bonded together, where the damage process is represented by the breakage of these bonds. Traditionally, fractures are modeled as an interface between 2 opposite blocks along which the particles are initially unbounded or simply deleting the particles from the fracture space for this type of fracture with a certain width . In this study, fractures are modeled by the method of deleting the bonds between particles.…”

“…Zhang carried out an experimental and numerical investigation on a double-flawed rock-like specimen subjected to uniaxial compression under different quasi-static strain rates [3]. Zhang prismatic specimens of brittle sandstone containing two non-coplanar fissures [6][7]. In these experimental and numerical studies on jointed rock mass specimens with two jointed fractures, the scopes of the inclination of the rock bridge, the dip angle of the joint fracture, the length of the rock bridge, and the length of the joint fracture are relatively small.…”

“…Bahaaddini et al [10] studied the effect of joint geometry parameters on the deformation modulus, compressive strength, and failure mode of the rock mass by particle flow modeling. Using photographic monitoring and acoustic emissions monitoring techniques, Yang et al [11,12] investigated the relationship between the real-time crack coalescence process and axial stress-time behavior for red sandstone containing two unparallel ssures. Chen et al [13] studied the in uences of joint inclination angle and joint connectivity rate on compression strength and stress-strain curves of rock mass with nonpersistent open joints by conducting uniaxial compression tests on gypsum specimens.…”
