The figure below picturizes a rock slope containing a planar sliding surface and a vertical tension crack. The tension crack is partly-filled with water due to the water table intersecting the slope face where the sliding surface daylights on the face. The water pressures in the tension crack and on the sliding surface are approximated by the triangular force diagrams illustrated in the figure. The slope has been reinforced by a tensioned rock anchor. Assume that; TIRTRIT TR A: the area of the sliding surface. c: the cohesion of the sliding surface : the internal friction angle of the sliding surface yp: the dip of the sliding surface. YT: anchor installation angle from the horizon. hw: the height of water column in the tension crack. Yw: the unit weight of water W: the weight of the block V and U: the water forces acting in the tension crack, and on the sliding plane, respectively. So, by taking this geometrical, physical, and mechanical circumstances into the account, derive the governing equation step by step, which defines the factor of safety (Fs) of this anchored, partially saturated slope. T: the tension in the anchor. L: Length of the sliding surface 1: the width of the block
