Fixing device and method for mounting irregular-structural-plane samples of various shapes

Abstract

The invention discloses a fixing device for mounting irregular-structural-plane samples of various shapes. The fixing device comprises a direction adjusting unit, wherein a flat plate is fixedly connected to the direction adjusting unit; a base is arranged on the flat plate; a bottom supporting plate is arranged in the middle of the base; the distance between the bottom supporting plate and the base is adjustable; the distance between the bottom supporting plate and the base is determined according to the height of a structural plane sample; a clamping unit is arranged on the base along a circumferential direction; the clamping unit comprises a hand wheel; the hand wheel is arranged on the base in a screw thread fit way; an upper end of the hand wheel is fixed at a lower end of a force application lever; an upper end of the force application lever is hinged to a lower end of a curved lever; an upper end of the curved lever is fixedly connected with a back end of a fan-shaped position adjuster; a clamping side plate is arranged at a front end of the fan-shaped position adjuster; an upper part of the curved lever is hinged with an upright post; a bottom end of the upright post is fixed on the base. The invention further discloses a fixing method for mounting irregular-structural-plane samples of various shapes with a shear apparatus. The fixing device and the fixing method are suitable for fixing irregular-structural-plane samples of various shapes, and are convenient for researching the anisotropy of structural planes.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a fixing device and method for installing multi-shaped irregular structural surface samples. Background technique [0002] The structural plane of rock mass refers to the geological interface or belt with a certain extension direction and length and relatively small thickness formed inside the rock mass during the development of geological history, including layers, joint surfaces, unconformity surfaces, etc. Due to the existence of structural planes, the continuity and integrity of the rock mass are greatly destroyed, and the mechanical properties and stability of the engineered rock mass are weakened. Therefore, it is of great significance to study the properties of the structural planes of rock mass. [0003] At present, the research on rock mass usually needs to process the rock mass into relatively regular cylinders or cubes before shearing, which is time-c...
