Experimental Study on Anchoring Effect of Rock Bolts to Fractured Rock Mass
Fractured rock mass is very prevalent in the rock engineering. With excavation perturbation, the joints and cracks will propagate, coalesce and lead to rock mass failure finally. It is well known that the rock bolt can achieve perfect anchoring effect in practice, especially in fractured rock mass. However, so far, the design of bolting is still more or less empirical. The present study aims to determine the effect of rock bolt on the behavior of fractured rock mass through physical experiments. In this research, a series of tests are performed considering different anchoring positions, anchoring angles and anchoring density. The results were contrastively analyzed both in quality and quantity. Several conclusions were drawn on the basis of analysis.
