Abstract

The invention discloses a method for simulating the schistosity structure of a rock sample in a rock-sample visualization experiment. The method comprises the following steps: (1) manufacturing a silica-gel mold; (2) weighing K39 resin and putting the K39 resin into a container; (3) preparing a compound hardening agent; (4) adding an accelerant; (5) adding the compound hardening agent; (6) pouring into hot water with the temperature of 30-40 DEG C; (7) adding a defoaming agent, stirring uniformly till no bubbles are generated, and preparing into K-glue mixed liquor; (8) prefabricating the schistosity structure; (9) fixing a thin film in the silica-gel mold; and (10) slowly pouring the prepared K-glue mixed liquor in the step (7) into the silica-gel mold along the wall of a container, standing for 1-2 hours, and then simulating out the schistosity structure in the rock sample in the rock-sample visualization experiment. The method disclosed by the invention has the advantages that the problem of no schistosity structure in the rock sample prepared by the existing method can be solved, and simulation for different schistosities in the rock sample is realized.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a method for simulating the rock sample slab structure in a rock sample visualization experiment. Background technique [0002] At present, in the rock sample visualization experiment, the prepared rock sample is obtained by injecting K39 resin material containing various auxiliary agents into a fixed mold, and making it solidify and shape under the condition of meeting multiple technical requirements and experimental conditions. The formed test piece is colorless and transparent, with very good visibility, and the strength and Poisson's ratio of the test piece can be changed by adjusting the auxiliary agent, which can simulate various rocks with different deformation parameters. However, the obtained transparent specimens are continuous without gaps and have no schistosity structure inside, but in reality there are a certain number of schistographs with differen...
