AI Technical Summary

Technical Problem

Existing technologies cannot realistically and controllably simulate the complex process of humidity-stress coupling in rock masses under natural environments in a laboratory setting, which limits a deeper understanding of the deformation and failure mechanisms of rock masses under dynamic humidity-mechanical interaction.

Method used

A multi-field coupled test system integrating temperature control, humidity regulation and mechanical loading was designed, including a mechanical loading module and an environmental control module. It can realistically and controllably reproduce the humidity-stress coupling evolution process of rock mass under natural environment in the laboratory, and dynamically monitor it through ultrasonic indenters and strain sensors.

Benefits of technology

This study achieved a comprehensive and systematic research on the mechanical properties of rocks, revealing the damage accumulation and failure mechanism of rock masses under the combined effects of humidity and stress, and providing experimental basis and theoretical support for the long-term stability assessment of geotechnical engineering.
