Abstract

The invention belongs to the field of rock strength testing, and relates to a rock uniaxial tensile test device and method. The device comprises a bonding centering device and a stretching device, wherein the bonding centering device comprises a support and a supporting seat, the support comprises two centering plates which are perpendicular to each other, and the supporting seat is used for supporting the support; the stretching device comprises two hanging rings, and the two hanging rings are connected through a pull rope; and connecting screw rods are arranged on the sides, away from the pull rope, of the two hanging rings. The centering problem of the rock sample and the puller when the diameter of the rock sample is different at different heights and in different directions can be well solved, and the problems that the two end surfaces of the rock sample are not parallel and the thickness of the adhesive is different can be well solved; the stretching device and method can ensure that the rock sample is subjected to pure tensile force, and effectively avoid bending moment and torque at two ends in the stretching process.

Description

technical field [0001] The invention belongs to the field of rock strength testing, and relates to a rock uniaxial tensile test device and method. Background technique [0002] During the excavation of rock slopes, excavation of foundation pits, and excavation of underground caverns, tensile stress will be generated in rocks at some positions (such as slope tops, pit tops, and vaults). The rock has strong compressive strength but weak tensile strength, and its tensile strength is generally 1 / 4 to 1 / 25 of the compressive strength, with an average of 1 / 10. Therefore, tensile stress can easily cause tensile failure of the rock, causing rock and soil damage. engineering disaster. In order to ensure the safety of the project, survey and experiment personnel are required to test the tensile modulus and tensile strength of the rock, so as to provide accurate tensile mechanical parameters for engineering design and construction. [0003] The most accurate method to test the tensil...
