Method for preparing schist similar materials

Abstract

The invention discloses a method for preparing a schist similar material. The method comprises the steps of mixing water, portland cement and mica plates in a certain proportion, discharging the stirred mixed materials into a mold through a discharging device, and after the materials are discharged, uniformly vibrating the materials by a vibrating table. According to the invention, portland cement is adopted as a gelatinization material and the mica plates are taken as aggregates, and thus the structure and construction characteristics of the schist similar material is close to those of schist relative to the structure and construction characteristics of the staggered inter-bedded similar materials; the adopted discharging device has the characteristics that materials can be discharged uniformly, and the integral mica plates are arranged in parallel, the operation is simple and easy, a convenient and feasible method is provided for researching the mechanical characteristics and the deformation damage mechanisms of the schist by utilizing the similar materials, the prepared similar materials have higher similarity with the schist compared with the conventional staggered inter-bedded similar materials.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, in particular to a method for making schist-like materials. Background technique [0002] Southwest China is covered by a large number of regional metamorphic rocks, most of which are schists. With the development of hydropower projects in Southwest China, more and more hydropower projects are facing problems of deformation and failure of schist, such as schist, collapse, slipping, etc. This requires an in-depth study of the physical and mechanical properties of schist. Due to the diagenesis of schist, the composition, sample selection and test results of schist have great discreteness, which is unfavorable to the study of schist. influences. Similar materials have the advantages of convenient sample preparation and small discreteness, and the advantages of controllable material selection have been widely used in experimental research. Schist has a schistostic structure and has ...
