Solved Problem on Soil Mechanics

Two different soil types (Soil 1 and Soil 2) are used as backfill behind a retaining wall as shown in the figure, where γt is total unit weight, and c' and φ' are effective cohesion and effective angle of shearing resistance

Solved Problem on Soil Mechanics

The soil profile above the rock surface for a 25o infinite slope is shown in the figure, where su is the undrained shear strength and γt is total unit weight. The slip will occur at a depth of

Solved Problem on Soil Mechanics

The soil profile below a lake with water level at elevation = 0 m and lake bottom at elevation = -10 m is shown in the figure, where k is the permeability coefficient. A piezometer (stand pipe) installed in the sand layer shows a reading of +10 m elevation.
