Stability Analysis of Rock Slopes with Plane and Wedge Failure by Means of a Pocket CalculatorAbstract:Although, in the investigation of the stability of a rock slope, the influence of several factors on the safety factor Fs has to be determined, it is not advantageous to use an explicit expression for Fs It can, in fact, be shown, that by dividing the forces into three groups, i.e. into the reactions (Ni, Si), the weight (W), and the resultant (R) of all the other forces acting in the system, a basic equation may be derived, in which the resultant R is on the left hand side of the equation. This basic formula has the following advantages:
