Abstract

The invention relates to an analog simulation material of a water-resisting layer in fluid-structure interaction and a preparation method of the analog simulation material, belonging to the technical field of hydrogeology and mining combined. The analog simulation material of the water-resisting layer in fluid-structure interaction is prepared from the following components: medium-coarse sands, gypsum, calcium carbonate, paraffin and vaseline, wherein the adulterate amount of paraffin in mass is greater than 8% of the sum of medium-coarse sands, gypsum and calcium carbonate but less than 15% of the sum of the medium-coarse sands, the gypsum and the calcium carbonate. The invention further provides a method for preparing the analog simulation material of the water-resisting layer in fluid-structure interaction. The analog simulation material of the water-resisting layer in fluid-structure interaction, which is provided by the invention, has the characteristics of being good in water resistance, maintaining the mechanical properties and providing beneficial reference for analog simulation and the like.

Description

technical field [0001] The invention relates to the technical field of combining hydrogeology and mining science, in particular to an aquifer-similar simulation material in fluid-solid coupling and a preparation method thereof. Background technique [0002] The similar simulation of the fluid-solid coupling problem has always been a difficult research point, mainly to study the water resistance of the materials used as the aquifer. Therefore, the research on the water resistance of materials with different ratio schemes is the basis of the fluid-solid coupling simulation experiment. In order to enhance the water resistance of experimental materials, the main additives currently selected are silicone oil, vaseline, and paraffin. There are few material formulations available for reference in the literature, and the results of using paraffin and vaseline at the same time to improve the water resistance of materials have not been considered.
