Abstract

The invention discloses a self-balancing rock all-end-surface true triaxial compression test device, which consists of a triaxial cell, a four link plate mechanism, a sigma 1 loading transfer system, a sigma 2 loading transfer system and a sigma 3 loading transfer system. The device is characterized in that the sigma 1 loading transfer system is positioned at the upper end of the triaxial cell and is connected with the triaxial cell through a piston in a sigma 1 direction; the sigma 2 loading transfer system is positioned at the side end of the triaxial cell and is connected with the triaxial cell through a piston in a sigma 2 direction; the sigma 3 loading transfer system is connected with the triaxial cell through a drain hole and a water inlet hole; and the four link plate mechanism is positioned inside the triaxial cell. The device can perform a plurality of tests on various rocks, and perform true triaxial compression tests on most of soluble rocks and undissolved rocks; the device can apply unidirectional pressure through water solution, and can perform a stress-dissolution coupling test on the soluble rocks; and the device can apply the stress on all end surfaces of a rock specimen to truly reflect the load bearing state of a rock body; and the test device has a simple structure, is easy to operate, and has a self-balancing function.

Description

technical field

[0001] The invention relates to the technical fields of geology and rock mass engineering, and more specifically relates to a self-balancing rock full-face true triaxial compression test device, which is mainly used for studying the basic mechanical properties of rocks and the stress of soluble rocks under complex combined stress states - Dissolution coupling characteristics, test results can be applied to geosciences and rock mass engineering research and rock mechanics. Background technique

[0002] Under natural conditions, the crust and engineering rock mass are deformed and destroyed under complex combined stress states. Rock mass is a complex geological body, which is in a complex three-dimensional stress field, and the failure of rock mass is usually caused by the change of its existing stress state. Conventional triaxial rock mechanics tests generally apply a certain confining pressure to the rock, and then keep the confining pressure constant (i.e. ...
