Test Study of the Damage-Fractured Process for Double Fractured Rock

Article Preview

Abstract:

Based on the rock mechanics test systems and the monitoring test of the acoustic emission (AE), the damage –fractured process for the double fractured rock is studied in order to gain the characteristics of deformation and damage evolution for the double fractured rock under the uniaxial compression. The damage evolution threshold value and the damage interpretation about the full stress-stain curve are given and the influence of initial damage on rock strength is analyzed. The results provide experimental foundation for engineering application.
