Abstract

The invention discloses a multiscale macroscopic-microscopic tester for rock and soil materials under multi-field coupling, which is suitable for real-time tracking measurement of the deformation and damage of rock and soil mediums under different coupling conditions of force-water-temperature. The tester comprises an MTS rigidity press, an airtight transparent testing box, a macroscopic optical camera, a microscopic optical camera, an LVDT displacement sensor, a humidity controller, a temperature-humidity sensor, a control and acquisition system and a rigidity working platform. The equipment has complete functions and high measurement precision, tracks the microscopic characteristics and the macroscopic representations of the material damage variation in real time, can realize the determination of mechanical parameters of the materials under the single-shaft condition and the identification of waterpower damage mechanism and long-term rheology mechanism, and is very suitable for the modern rock and soil research demands.

Description

technical field [0001] The invention relates to the technical field of experimental measuring instruments, more specifically to a multi-field coupling multi-scale macro-microscopic testing machine for rock-soil materials, which is suitable for real-time deformation and damage of rock-soil media under different coupling conditions of force-water-temperature Tracking measurement can realize the determination of material mechanical parameters under uniaxial conditions, the identification of hydraulic damage mechanism and long-term rheological mechanism. Background technique [0002] Geotechnical materials are affected by various coupling effects such as different force-water-temperature-chemical in the process of engineering construction, operation and maintenance, especially in deep underground projects (oil, natural gas strategic energy storage, high-level radioactive nuclear waste storage, development of unconventional oil and gas fields) is more prominent. At the same time...
