02:11, 3 August 2023 [email protected] talk contribs created page Stability During and at the End of Construction (Created page with ""Computations of stability during construction and at the end of construction are performed using drained strengths in free-draining materials and undrained strengths in materials that drain slowly. Consolidation analyses can be used to determine what degree of drainage may develop during the construction period. As a rough guideline, materials with values of permeability greater than 10-4 cm/sec usually will be fully drained throughout construction. Materials wi...")
02:11, 3 August 2023 [email protected] talk contribs created page Stability During Steady State Seepage Conditions (Created page with ""Long-term stability computations are performed for conditions that will exist a sufficient length of time after construction for steady-state seepage or hydrostatic conditions to develop. (Hydrostatic conditions are a special case of steady-state seepage, in which there is no flow.) Stability computations are performed using shear strengths expressed in terms of effective stresses, with pore pressures appropriate for the long-term condition." <ref> https://www.p...")
02:11, 3 August 2023 [email protected] talk contribs created page Stability During Sudden Drawdown (Created page with ""Sudden drawdown stability computations are performed for conditions occurring when the water level adjacent to the slope is lowered rapidly. For analysis purposes, it is assumed that drawdown is very fast, and no drainage occurs in materials with low permeability; thus the term “sudden” drawdown. Materials with values of permeability greater than 10-4 cm/sec can be assumed to drain during drawdown, and drained strengths are used for these materials." <ref> https...")
