An example application of Bishop’s method is given by Hoek and Bray for the case of a slope
excavated in highly weathered granitic rock. The slope contains three 15 m high benches with two
8 m wide beams. The bench faces are inclined at 75◦ to the horizontal, and the top of the slope is
cut at 45◦ from the top of the third bench to the ground surface. Figure 10.1 illustrates the geometry of the slope.
