Abstract

The invention discloses a rock tensile strength test apparatus capable of applying confining pressure, which can truly restore an environment in which rock is disposed. The rock tensile strength test apparatus comprises a base, wherein the base is connected with a top plate by virtue of a connecting rod; and the base is fixedly provided with a test assembly, the top plate is fixedly provided with a loading oil cylinder, and a loading rod of the loading oil cylinder stretches into the test assembly. By adopting the rock tensile strength test apparatus, the confining pressure, different temperature environments and rock burst can be applied to a test sample, an underground environmental condition of the rock can be truly simulated, so that an underground stress condition of the rock and the variation of tensile strength can be more precisely researched, and instructions and references can be provided for the subsequent design, construction, teaching, research and the like. By adopting the rock tensile strength test apparatus, the test sample can be rapidly centered, and a breaking time and pressure at the breaking time of the test sample can be discovered in time by virtue of a displacement of the loading rod. By virtue of a cooling assembly, heat of the loading rod and a lower supporting rod can be prevented from damaging the test apparatus.

Description

technical field [0001] The invention relates to a rock tensile strength testing device, in particular to a testing device capable of confining pressure and testing the rock tensile strength by the Brazilian method. [0002] The present invention also relates to a temperature control system and a temperature control method based on the above test device. Background technique [0003] In the study of rock mechanical properties, the tensile strength of rock is one of the research focuses. At present, there are two main methods for studying the tensile strength of rocks, one is the Brazilian disc splitting method, and the other is the direct tension method. [0004] Testing the tensile strength of rocks by the Brazilian disc splitting method is the main testing method at present. The equipment is relatively simple and easy to operate. Therefore, this method is basically used in ordinary teaching and testing at present. At present, there are many experimental devices designed u...
