Based on smooth particle hydrodynamics (SPH) method, this paper carried out the numerical simulation of ultra-high-pressure water jet (UHP-WJ) impacting steel fiber reinforced concrete (SFRC), verified the established numerical model by UHP-WJ impacting SFRC and computed tomography (CT) scanning experiments, and explored breaking mechanism and damage evolution rule of SFRC impacted by UHP-WJ. Results indicate that in the weak effect zone of steel fiber, the failure of concrete is generated and developed along the axial direction of UHP-WJ into a bowl-shaped crater with the combining action of compressive stress and shear stress. In the affected area of steel fiber, due to the inhomogeneity in the contact area of steel fiber and concrete, the stress concentration in the contact area is produced, causing the formation of propagated crack along the steel fiber. And the steel fiber has an obstruction effect on the development of broken bodies on the upper and lower sides of steel fiber. With the sustained action of UHP-WJ, the steel fiber in the intense radiation area of stress waves takes place fracture and finally the broken bodies on the upper and lower sides of steel fiber fuse. In addition, based on the CT scans and digital image processing technology, this paper also comparatively analyzed the internal fragmentations of SFRC and the ordinary concrete subjected to UHP-WJ impact, and it is found that compared with the ordinary concrete, there is smaller dimension of crater and it is difficult to engender macrocrack for SFRC, with lower damage and higher damage attenuation speed along the axial and radial directions.

“…In current research, cracks are approximately expressed mainly through element deletion or element damage [19,20] . Having low computational efficiency for a large-scale model, the particle flow code, discrete element and extended finite element methods are applicable for exploring test blocks at experimental scale [21,22,23] . Cohesive element has the advantages of high computational efficiency and good convergence in analyzing crack propagation [24,25] .…”

To explore the distribution of cracks in anchored caverns under the blast load, cohesive elements with zero thickness were employed to simulate crack propagation through numerical analysis based on a similar model test. Furthermore, the crack propagation process in anchored caverns under top explosion was analysed and the distribution and mode of propagation of cracks in anchored caverns when a fracture with different dip angles was present in the vault were discussed. With the propagation of the explosive stress waves, cracks successively occur at the boundary of the anchored zone of the vault, arch foot, and floor of the anchored caverns. Tensile cracks are preliminarily found in rocks surrounding the caverns. In the case that a pre-fabricated fracture is present in the upper part of the vault, the number of cracks at the boundary of the anchored zone of the vault decreases, then increases with increasing dip angle of the pre-fabricated fracture. The fewest cracks at the boundary of the anchored zone occur if the dip angle of the pre-fabricated fracture is 45º. The wing cracks deflected to the vault are formed at the tip of the pre-fabricated fracture, around which tensile and shear cracks are synchronously present. Under top explosion, both the peak displacement and peak particle velocity in surrounding rocks of anchored caverns reach their maximum values at the vault, successively followed by the side wall and the floor. In addition, they show asymmetry with the difference of the dip angle of the pre-fabricated fracture; the vault displacement of anchored caverns is mainly attributed to the formation of tensile cracks at the boundary of the anchored zone generated due to tensile waves reflected from the free face of the vault. When a fracture is present in the vault, the peak displacement of the vault decreases while the residual displacement increases.
