Question
(e) Using Stereonet Projection (Figure Q5-e), determine and discuss the stability of a set of joint planes dipping at 36° with a dip direction of 123*, daylighting on the face of a wall slope dipping at 62° with the same dip direction 123° Joint set planes are assumed to have no cohesive resistance and the friction angle () of all joints in the joint set is assumed to be 31°.
