Simulation Analysis of Mechanical Properties of Marble Containing Hole with Weak Intercalation

Abstract

Abstract: To study the failure mode and mechanical properties of marble with one weak intercalation and central hole under uniaxial compression, the fracture process of the sample is simulated by the numerical simulation software RFPA2D. The results show that the existence of the weak intercalation changes the failure mode of the marble sample. When the strength of the weak intercalation is lower and the thickness is larger, the marble under the weak intercalation basically does not appear failure. When the strength of the weak intercalation is unchanged, the peak stress of the marble sample decreases with the increase of the thickness of the weak intercalation, and the strain corresponding to the peak stress increases with the increase of the thickness of the weak intercalation. When the thickness of the weak intercalation is constant, the peak stress of marble sample increases with the increase of the strength of the weak intercalation, and the strain corresponding to the peak stress decreases with the increase of the strength of the weak intercalation. The results reveal the failure mode and mechanical characteristics of marble containing holes with different thickness and strength weak intercalation, which provides some reference for the instability failure of the rock mass engineering in the upper part of the weak intercalation.
