Abstract

The invention discloses a fracture-pore double-permeation medium dominant flow simulation device and an experimental method, and belongs to the technical field of geological engineering. The simulation device comprises a support, the support is detachably connected with a transparent container, the interior of the transparent container is filled with a fracture-pore double-permeation medium experiment model, the top of the transparent container is open, a leaching device is arranged above the transparent container, and the bottom of the transparent container is provided with a liquid rapid outflow port connected with a liquid collection device. The invention further discloses an experimental method of the simulation device and a manufacturing method of a fracture-pore double-permeation medium experiment model. The simulation device can highlight and enhance the dominant seepage experiment effect, experiment process is visualized by placing the manufactured fracture-pore double-permeation medium experiment model in the transparent container, and formation of dominant flow is observed at any time; material manufacturing, experiment process displaying and result analysis are modeled and informationalized, and requirement for a lab is lowered.

Description

technical field [0001] The invention relates to the technical field of geological engineering, in particular to a simulation device and an experimental method for a dominant flow of a fracture-pore dual-permeability medium. Background technique [0002] For rock-soil media with fracture-pore dual-permeability properties, the simulation experiment study of its dominant seepage is an important means in the fields of geological engineering, groundwater science, geotechnical engineering, and petroleum engineering. [0003] Due to the difference in pores, the fractured-porous double-permeable rock-soil medium is easy to cause the formation of dominant flow, which has great impact on geological environmental disasters such as rock-soil geological disasters, soil salinization, vadose zone seepage, and tundra formation. Problem research is of great significance. [0004] The main technical difficulty in the above-mentioned fields is to make the dominant seepage flow of the medium w...
