Abstract

The invention discloses a testing device for the unconfined compression fluid deformation of a solution environmental action rock mass. The testing device is characterized by comprising a corrosion-resistant solution vat, a corrosion-resistant base, a corrosion-resistant press head, fixed bar racks and a press bar, wherein the corrosion-resistant base is fixed at the bottom of the corrosion-resistant solution vat; the fixed bar racks are located at both sides of the corrosion-resistant solution vat, the press bar is arranged on the fixed bar racks, is located right above the corrosion-resistant solution vat and can move up and down along the fixed bar racks; a position on the lower part of the press bar corresponding to the corrosion-resistant base is provided with the corrosion-resistant press head; and when being used, a test piece is soaked in the corrosion-resistant solution vat filled with solution and is put between the corrosion-resistant base and the corrosion-resistant press head, both ends of the press bar are loaded with weights, and simultaneously the upper part of the press bar is connected with a displacement micrometer gauge used for measuring the deformation degree of the test piece. The testing device has simple structure and low cost, so the testing device is especially suitable for extensive popularization in the unconfined compression fluid deformation test of the solution environmental action rock mass.

Description

technical field [0001] The invention relates to a test device for uniaxial rheology under the action of water-rock, in particular to a device capable of reflecting the rheological characteristics of rock mass containing structural planes under the action of solution corrosion. Background technique [0002] Rheological phenomenon is a relatively common phenomenon in rock and soil mass, which refers to the phenomenon that the deformation of rock mass changes with time under a certain force. The currently known rock rheology is regarded as an inherent mechanical property of rock, and the testing instruments are relatively expensive. In fact, the rock mass is a complex medium containing many structural planes. In many cases, the rock mass is in the groundwater environment, and the groundwater rich in various complex components has complex interactions with the rock mass. Important cause of rheology. Most of the traditional methods focus on the rheological properties of the roc...
