AI Technical Summary
Existing technologies are insufficient to realistically simulate high ground stress environments in deep rock blasting, and optical observations during blasting are affected by explosion light and debris, resulting in significant discrepancies between experimental results and actual field conditions.
By employing transparent rock specimens, a transparent true triaxial dynamic-static combined loading system, a high-pressure mixed oil blasting system, and a dynamic photoelastic observation system, combined with a synchronous control and data analysis system, we can achieve three-dimensional stress field simulation of deep rock and soil and visualization of the entire blasting stress-strain process.
It enables full-field, real-time, and quantitative visualization of the blasting process in deep rock and soil, avoiding interference from explosion light and debris, and improving the accuracy and reliability of experimental data.
