Osmotic Pressure and Temperature Coupling Simulation Device and Method Based on True Triaxial Electromagnetic Loading

Abstract

This invention relates to the field of rock mechanics engineering technology and discloses a device and method for simulating the coupling of osmotic pressure and temperature based on true triaxial electromagnetic loading. The device includes a triaxial electromagnetic loading assembly, a test chamber, six dynamic sealing assemblies, an osmotic pressure assembly, a heating assembly, and a data acquisition assembly. The test chamber is located in the middle of the triaxial electromagnetic loading assembly, with six surface openings that cooperate with waveguide rods. The six sets of dynamic sealing assemblies seal the openings and gaps between the sealing assemblies and the waveguide rods to form a sealed cavity. The osmotic pressure assembly connects to the sealed cavity, the heating assembly is located in the test chamber, and the data acquisition assembly collects experimental data. This structure enables synchronous dynamic loading in three axes and six directions, and allows for precise synchronous control of osmotic pressure and temperature within the sealed cavity during dynamic loading. It solves the problem of traditional devices only performing single-axis dynamic loading and being unable to collaboratively simulate multi-field coupling environments, realistically reproducing the environment of deep rock masses with "high ground stress, high ground temperature, and high osmotic pressure" coupled with multi-axis and multi-directional dynamic disturbances.
