Hydrostatic pressure, arching of the soil and electro-osmotic forces have each been suggested as the dominant factor to account for stability of trench excavations in cohesionless soils supported by clay slurries. The Authors suggest that the most important mechanism is the hydrostatic pressure...
Within the framework of limit equilibrium methods of stability analysis, no restriction need be placed at the outset upon the shape of the possible slip surface. In many cases, the critical surface may deviate significantly from a circle or a plane and therefore a method that facilitates the...
Stability charts are presented to facilitate the computation of the factor of safety of earth slopes during rapid drawdown. As the reservoir level is lowered, the factor of safety decreases if it be assumed that no dissipation of pore pressure occurs during drawdown. Pore pressures during...
