AI Technical Summary
Existing technologies lack effective testing equipment for tensile testing and synchronous ultrasonic testing of rock joints under multi-field coupling, resulting in insufficient research on the tensile failure mechanism of jointed rock masses and the influence of wave propagation, especially under high stress-temperature-water multi-field environments.
A multi-field coupled rock joint tensile and synchronous ultrasonic testing device was designed, including a first tensile connecting member, a second tensile connecting member and a third tensile connecting member, and combined with an osmotic pressure control module, a confining pressure control module and a temperature control module to realize synchronous testing.
It can accurately study the direct correlation between joint tensile mechanical properties and wave propagation characteristics under multi-field coupling, improve the accuracy and reliability of experiments, and study the impact of rock mass engineering stability and seismic wave propagation.
