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...
