Digital technology-based irregular rock sample point load rapid testing device and method

Abstract

The present application relates to point load test technical field, especially irregular rock sample point load fast testing device and method based on digital technology, testing device includes point load tester, the guiding plate is arranged on the point load tester and slides, the guiding plate both sides symmetrically are provided with bearing assembly, the bearing assembly is installed on the adjusting assembly, the adjusting assembly includes movable mounting plate, the camera is rotatably arranged at both ends of mounting plate respectively, two cameras shoot two sample images of left and right two visual angles of the sample; the test method is applied to the testing device, the sample image is corrected, extraction processing, stereo matching, three-dimensional reconstruction processing, the split surface triangulation reconstruction model of the damaged sample is obtained, the projection plane is established in two split surface triangulation reconstruction models of the damaged sample, the sample split surface projection calculation area is obtained, the point load strength index is calculated according to equivalent area calculation formula;The present application carries out point load test to irregular different types of rock sample, improves the measurement accuracy and test efficiency.
