Saturated Sand as an Inelastic Two-Phase Medium.

摘要: The inelastic densification produced by shear straining saturated sands is opposed the elasticity of pore water and leads to a pressure increase, which causes decrease in intergranular frictional forces consequent liquefaction sand mass. This accompanied an strain fluid phase, magnitude developed product compliance, latter being approximately equal drained compressibility sand. tangent elastic moduli are expressed terms undrained compressibilities two-phase medium solid matter forming grains. It demonstrated that volume change grains due stresses has negligible effect on material parameters, even though it roughly equals pressure, appreciable effect. Typical values calculated for parameters.
