Experimental Study on Failure Characteristics of Rock-Like Material with Prefabricated Primary and Secondary Cracks
Abstract The crack propagation of rock material is an important research topic in the field of geotechnical engineering, which has important theoretical guiding significance for engineering design, construction, monitoring and maintenance. To explore the effect of prefabricated cracks on the crack propagation and rock failure characteristics of rock, the rock-like material was used to perform uniaxial compression tests on five sets of specimens with prefabricated primary and secondary cracks. It was shown that in all crack combinations, the crack firstly originated from the tip of the primary crack. When the primary and secondary cracks intersected, the crack at the tip of the secondary crack initiated later, and only the end far away from the primary crack initiated; When the primary and secondary crack was separated, the primary and secondary crack tips cracked almost at the same time; All specimens under uniaxial compression were ultimately dominated by tensile failure; the larger the distance between the primary and secondary cracks, the smaller the peak strength and the possibility of penetration.
