A long natural slope in an over-consolidated clay (c'=10kPa, φ'=25deg, γsat=20kN/m3) is inclined at 10 degrees to the horizontal. The water table is at the surface and the seepage is parallel to the slope. If a plane slip had developed at a depth of 5m below the surface, determine the factor of safety. Use γwater=10kN/m3.
A highway embankment is to be constructed of height 10m over a soft clay deposit of 10m thick overlying firm dense sand. The soft clay has an undrained cohesion of 37.5kN/m² and unit weight of y = 17.5kN/m³. It is decided to adopt stone column technique to improve the load carrying capacity of soft clay deposit.

A large embankment is to be built on the surface of a 18-ft clay layer. Before the embankment is built, the initial σ′v at the middle of the clay layer is 500 psf. The results from a 1-D consolidation test on the clay from the middle of the layer provide σ′p=1600 psf, Crε=0.0352, and Ccε=0.180. If the final σ′v at the middle of the layer after the embankment loading is 2000 psf, what is the settlement, in inches, of the clay layer resulting from thisloading?
