. A long natural slope in fissured overconsolidated clay is inclined to the horizontal with an angle =15 o . The saturated unit weight of clay is 18 kN/m3 . The water table is at the surface and the seepage is roughly parallel to the slope. A slip has developed on a plane parallel to the surface at the depth of 4.0 m. Find the factor of safety along the slip plane, for the following two cases: a. Peak shear...

A proposed residential development of a single tower is to be built on a sloping site as shown in Figure 1. The site has a (W1m x 25m wide building zone. A level platform has to be created by building a permanent retaining structure outside the building zone but within the (W2m x (W2m wide site boundary. A temporary slope, which may extend outside the site boundary, has to be formed in advance for construction of the retaining structure. ---...
