Embodiment 1

[0044]The invention is used in cooperation with a thin-layer cutting device for multi-interlayer model materials and a soft thin-layer adsorption and translation device for model materials. According to the physical and mechanical properties of each layer of the multi-interlayer composite rock mass, the present invention mixes a variety of similar model materials; uses a thin-layer cutting device for multi-interlayer model materials to slice various model material blocks to obtain Model material thin layer; then use a model material soft thin layer adsorption translation device to alternately superimpose the thin layers of different materials obtained by cutting, and lay bonding materials on the interface when superimposing according to the test requirements; then, superimpose The final model material block is placed on a pressure testing machine, and it is pressurized to make it consolidate until it meets the test requirements, and an interactive layered model material block i...

Abstract

The invention discloses a method for preparing an interactive laminar modeling material test piece. The method comprises the following steps of: A, preparing a modeling material: (1) preparing a material a, namely placing loess and barite powder in a stirrer, uniformly stirring the materials and adding water into the mixture to obtain a plastic mixed material a; (2) preparing a material b, namely placing cement and loess into the stirrer, uniformly stirring the materials and adding water into the mixture to obtain the plastic mixed material b; B, assembling detachable boxes; C, pre-pressing: placing the prepared material a and material b in the boxes, arranging pressing plates on the boxes respectively and placing the boxes on an MTS pressure tester for pressing; D, slicing; E, adsorbing, translating and superposing; F, repairing and repressing; G, solidifying; and H, machining the test piece: manufacturing the interactive laminar standard test pieces with different bed inclinations. The method has the advantages of simple and definite process flow, high efficiency, reduction in manufacturing period, high reliability, uniform manufacturing of thin modeling material layer at each layer, broad application prospect and obvious economic benefit.

Description

technical field [0001] The invention relates to the technical field of rock mechanics tests, and more specifically relates to a preparation method for processing model materials into interactive layered test pieces, which is suitable for physical simulation tests on layered composite rock masses. Background technique [0002] In the design and construction of underground engineering, mining engineering, oil and gas nuclear waste storage and other engineering structures, there are a large number of interbedded composite rock mechanics problems related to sedimentary rock formations. Since the interbedded composite rock mass is a natural layered material composed of a variety of different properties, different thicknesses, different components and different combinations in a certain order, its mechanical and deformation properties reflect the heterogeneity of the multiphase properties, anisotropy, interlayer mechanical properties, composite mechanical effects, and mismatching ...
