Abstract
The influence of the flaw (joint or fracture) distribution, the flaw length and bridge length (the distance between two flaws) on the coalescence and failure mechanism, and the peak strength of rock mass containing multi-cracks are studied under the uniaxial and biaxial loading. Based on the physical experimental testing and numerical simulation (with a newly developed code RFPA2D), it is found that the behavior of multi-crack coalescence, the pattern of failure and peak strength are sensibly affected by the flaw number, the flaw length, bridge length and confining pressure.
