The Electrical Resistivity and Acoustic Emission Response Law and Damage Evolution of Limestone in Brazilian Split Test

Abstract: The Brazilian split test was performed on two groups of limestone samples with loading directions vertical and parallel to the bedding plane, and the response laws of the electrical resistivity and acoustic emission (AE) in the two loading modes were obtained. The test results showed that the Brazilian split test with loading directions vertical and parallel to the bedding showed obviously different results and anisotropic characteristics. On the basis of the response laws of the electrical resistivity and AE,… Show more

“…Li [25] investigated the mechanical behaviors and the variations in acoustic emission characteristic parameters, including event counts, cumulative counts, and energy, during the uniaxial compression failure process of sandstone. Xu [26] studied the variations in acoustic emission event counts and duration during the fracture failure process of limestone specimens. Wang [27] investigated the frequency-domain variations in acoustic emission energy during the failure process of limestone under Brazilian splitting loading conditions.…”

“…Failure of brittle rock normally initiates from tensile fracture due to its extraordinary lower resistance to tension rather than to compression [2]. In many engineering applications, parameters such as the stability of the chamber excavation and hydraulic fracturing largely depend on the tensile strength of the rock [3,4]. erefore, it is necessary to accurately determine the tensile properties of the layered rock mass.…”
