Description

Technical field [0001] The present invention relates to the field of rocky molecular weight research, and in particular to a study method based on the microstructure and properties of the molecular-level rock. Background technique [0002] The rock is a collection of one or several minerals, the external performance of the rock and the macro physical mechanical properties are closely related to the microstructure of the inherent mineral crystals and the micro-physical chemical properties, and study the micro-characteristics of rock minerals to master the rock macro physics. The microscopic nature mechanism of mechanical properties is of great significance. At present, the research on the microscopic characteristics of rocks is concentrated on a fine scale, such as Feng Xia Ting et al. CT (ComputerizedTomography) test under the corrosion of chemical solution, and studied the development process of rock from microcracks to the destruction; Zhang Yuan et al. High-temperature microsc...

Problems solved by technology

The above studies either use microscopes and CT scanning techniques to observe and analyze rock mesoscopic damage and fracture processes, or extract the content of certain parameters in the mesoscopic structure to fit and establish the relationship with mechanical strength to explain the macroscopic physical properties of rocks. The relationship between mechanical properties and rock mesostructure has not yet revealed the microscopic essential mechanism of rock macroscopic physical and mechanical properties from the microscopic scale
