SAMPLE FIXTURE FOR INDIRECT TENSILE TEST OF ROCK MASS

原文（中国語）

Provided is a sample fixture for an indirect tensile test of rock mass, relating to the technical field of rock mass engineering geomechanics tests. The sample fixture includes an upper fixture, and a lower fixture located below the upper fixture. The upper fixture includes an upper fixing block, a ball head, and an upper knife. The lower fixture includes a lower fixing block, a telescopic positioning plate, and a lower knife. The ball head is in fit with a spherical groove on an upper surface of the upper fixing block to achieve the function of transferring pressure, thus ensuring loading strength acting on a sample. A loading force is transferred by using a cutting edge of the upper knife to make the pressure act on the sample intensively, thus ensuring point or linear loading required by the test.
