Anchorage Effect on Fractured Rock and Cavern Stability

Abstract:

Article Preview

The effect of anchor on fractured rock specimens in splitting test is simulated by DDARF method in this research. The results are compared and agree well with laboratory test results. The DDARF program is also adopted to analyze the stability of an underground cavern with four groups of randomly generated joints in the surrounding rocks, in which two conditions with and without rock bolts are considered. Besides, the crack propagation process around the cavern and the displacements of key points in the surrounding rock are monitored and applied to investigate the stability of the cavern.
