Method for manufacturing transparent rock model structure face test piece

Abstract

The invention discloses a method for manufacturing a transparent rock model structure face test piece. The method comprises the following steps that 1, a protolith structural face is manufactured; 2, the structural face is placed in a stainless steel mold; 3, a silica gel opposite model of the protolith structural face is manufactured; 4, transparent epoxy resin is weighed and placed in a container; 5, a curing agent is added into the container in the step 4, and bubbles in the stirred mixed solution are removed through light vibration in the vacuum negative pressure environment; 6, the silica gel opposite model manufactured in the step 3 is placed in the mold in the step 2; 7, the mixed solution prepared in the step 5 is slowly poured into the mold in the vacuum negative pressure environment, and pouring is stopped after the solution reaches a certain position; 8, a transparent epoxy resin cube body custom-made in a factory is placed in the mixed solution which is not cured, the two parts are horizontally bound, and a simulation structural face capable of being used for a rock visualization experiment is obtained. The fine surface form of the structural face is effectively and truly reflected, and good transparency and repeatability are achieved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering in civil engineering, in particular to a method for manufacturing a transparent rock model structure test piece. Background technique [0002] The rock mass in nature produces various structural planes due to complex geological processes, and these structural planes affect the mechanical and seepage characteristics of jointed rock mass to a large extent. Since the rock cannot be directly seen through visible light, the traditional rock test cannot observe the change of the internal geometry of the rock during the test, so it is impossible to know the microscopic phenomena such as the generation of internal cracks during the rock’s stress failure process, and the transparent rock made of similar materials Test pieces can solve this major problem. The current simulated rock transparent specimens are made by the overall solidification molding method. The molded specimens have high t...
