Transcribed Image Text:

Surface of a granular soil mass is inclined at 250 to the horizontal. The soil is saturated throughout with a moisture content of 15.8 percent, particle specific gravity of 2.65 and a friction angle of 380. At the depth of 1.83m water is seeping through the soil parallel to the surface. Determine the safety factor against sliding on a plane parallel to the surface at a depth of 3.05m below the surface (y = 10 kN/m3). What would be the safety factor for the same plane if the level of the seeping water lifted up to the surface of the soil? Surface of a granular soil mass is inclined at 250 to the horizontal.
