Embodiment Construction

[0028] The invention discloses a sample preparation method for simulating a complex rock mass containing multi-layer interlayer dislocation zones and columnar joints, comprising a columnar joint structure 1, a constraint plate 2, a U-shaped splint 3, a sample preparation base 4 and an inclination control mechanism 5.

[0029] The columnar joint structure 1 is completed by high-precision 3D printing technology, and the strength of the columnar joint structure is adjusted by adjusting the fineness of printing. The finer the printing, the smaller the thickness of the columnar joints and the higher the strength of the columnar joints.

[0030] In the sample preparation mould, the constraint plate 2 has a plurality of pieces, which are connected and fixed by a connecting mechanism to form a mold cavity. The surface of the constraint plate 2 is provided with a scale line along its length direction, and the back of the constraint plate 2 is provided with a circle. Arc-shaped grooves ...

Abstract

The invention discloses a sample preparation mold and a sample preparation method for a complex rock mass structure containing multiple interlayer staggered belts and columnar joints. The sample preparation mold comprises a restraint plate, a connecting mechanism, a sample preparation base and an inclination angle control mechanism (5); scale marks are arranged on the surface of a restraint plate of the sample preparation mechanism, and simulation positions of a bed rock mass, an interlayer staggered belt and a columnar jointed rock mass can be calibrated through scale setting; the columnar joint structure is realized through a 3D printing technology; the sample preparation mold provided by the invention is simple in structure, can be used for accurately and quickly preparing a simulation sample containing a multi-layer interlayer staggered belt and columnar joint complex rock mass structure, and is beneficial to experimental research on permeation, strength and deformation behaviors of the interlayer staggered belt and columnar joint complex rock mass, so that an accurate and reliable test result is obtained.

Description

technical field [0001] The invention relates to a sample preparation method for simulating complex rock masses containing multi-layer interlayer dislocation zones and columnar joints. Background technique [0002] The complex rock mass with multi-layer interlayer dislocation zone and columnar joints is a special structural rock mass with discontinuous and nonlinear characteristics. The complex structure of interlayer dislocation zone and columnar joints has a significant impact on the stability of the rock mass. Therefore, it is necessary to study the mechanical properties of complex rock mass with interlayer dislocation zones and columnar joints. [0003] Rock mechanics tests mainly include on-site tests and indoor tests, among which in-situ tests have poor economic benefits and are significantly affected by the environment. In recent years, many scholars at home and abroad have studied the mechanical behavior of rock mass with interlayer dislocation zone and columnar join...
