TECHNICAL NOTE. A SHORT SOLUTION FOR THE STABILITY OF A ROCK SLOPE CONTAINING A TETRAHEDRAL WEDGE

To assist the engineer wishing to make a quick assessment, a solution is presented for the computation of the factor of safety against translational slip of a tetrahedral wedge formed in a rock slope by two intersecting discontinuities, the slope face and the upper ground surface. It does not take into account rotational slip or toppling. The solution allows for different strength parameters and water pressures on the two planes of weakness. It is assumed that the slope crest is horizontal, i.e. The upper ground surface is either horizontal or dips in the same direction as the slope face or at 180 degrees this direction. /TRRL/
