| In this research geometric classification of rock blokes shapes that produces from exist the relationships among a variation of inclination of slope (45°,90°,45° towardsrock mass), a variation in bedding plan dip (90°,45°,0, 45°towards rock mass), and a variation in discontinuities dip 90°,45°,*45° (towards rock mass) in parallel strikes case (with equal spacing approximately), also to observing the extent of their influence on slope stability and the possible failure type in it. The classification includes(36) class, each class results from possibility of existence of parallel sets of discontinuities (with equal spacing approximately) (one set d1 or d2 or d3 or two sets d1 and d2 or d2 and d3 or d1 and d3 or three sets d1,d2, and d3), which (d1) represents perpendicular discontinuities, (d2) a dipping discontinuities (45°) with direction of slope, (d3) a dipping discontinuities (*45°)towards the rock mass ,and the (sd1,sd2,sd3) represents the spacing between discontinuities of (d1,d2,d3) respectively with variation of bedding plan dipping(with equal spacing approximately) (sb), and with variation of active slope inclination (s.s) according to the above angels, these cases might give rock blocks with different shape, dimensions, in same class. Each class and its models in the proposal classification are represented by block diagrams and stereographic projection. | ||
