The probability patterns of rock masses of slope are calculated and simulated with the aid of the Monto Carlo method on the basis of survey data of discontinuity. Consequently, the two dimentional RQD in the range of 360° of rock slope is estimated and the concept of orientation RQD is proposed. Finally, the method of orientation RQD is applied into a research to find out the relationship between ra...
