Abstract

The presence of numerous open joints and complex three-dimensional (3D) geometrical characteristics in natural rock masses creates structural discontinuities that significantly impact stress-wave propagation and the rock’s damage and failure behaviors. In this study, specimens featuring open joints were prepared using 3D printing techniques, and an indoor 3D blasting experiment was conducted at dig angles of 50°, 70°, and 90°. Computed tomography (CT) scans and subsequent 3D reconstructions were employed to analyze the 3D distribution of cracks in the blasted specimens. The blasting process on a rock mass with open joints was inversely deduced using the numerical simulation software AUTODYN, considering the evolution of stress-wave propagation and blasting-induced damage as a function of the open joint dip angle. The results revealed the formation of blast-induced cracks primarily at the ends of the open joints, accompanied by circumferential cracks on the outer surface surrounding the projected joint profile. The incident angle of the stress wave compromised the stressed state at the joint ends, resulting in variations in crack distribution patterns on the back-blast side. As the joint dip angle increased, both the fractal dimension and specimen damage escalated, while the inhibitory effect of the 3D open joint face on crack propagation weakened. The dip angle of the joint face significantly influences the form and intensity of the stress wave. When the stress wave is vertically incident, bypassing waves at the lower and upper ends, along with the wave transmitted in the middle, cause the open joint face to close under stress. Consequently, the stress and damage fields exhibit a weakening effect on the side closer to the blast and an intensification effect on the opposite side.

Highlights

  1. 1.

    Specimens featuring opening joints were prepared using 3D printing, and the fracture modes of joints with varying opening angles under blasting loads were examined.

  2. 2.

    The spatial configuration of 3D cracks was reconstructed, and an analysis was conducted to determine how the opening joint angle influenced the spatial distribution of these cracks during rock blasting.

  3. 3.

    A 3D numerical model of a rock mass with open joints was implemented, allowing analysis of the interaction between explosive stress waves and internal open joint planes. In addition, the evolution of damage within the rock mass was studied.
