| Abstract: | Engineering rock mass is always bursted and crushed along its discontinuities. Quantifing deterioration of rock mass with discontinuities becomes a basis for prospecting and designing engineering rock mass. Several methods for quantification of rock quality are presented and discussed in this paper. Finally, we proposed a trend in quantification of rock quality. |
