A Theory of the Consolidation of Snow
Abstract A consolidation theory is developed for an age-hardened snow under uniaxial stress in the porosity range of 35 to 55 per cent by considering one mechanism, viz. viscous flow of interparticle bonds. For a uniaxial stress σ the differential equation for porosity n in terms of time t is shown...

| Summary: | Abstract A consolidation theory is developed for an age-hardened snow under uniaxial stress in the porosity range of 35 to 55 per cent by considering one mechanism, viz. viscous flow of interparticle bonds. For a uniaxial stress σ the differential equation for porosity n in terms of time t is shown to be where a and ν are structural parameters and η is the coefficient of viscosity of ice. Comparison of this equation and the integrated form with existing data predicts consistent and reasonable values for a . The predicted values of η / ν range from 10 −2 to 10 2 times the published values for, η which may indicate that ν , and hence the consolidation rate, is greatly affected by the diagenetic history of the snow and the conditions of experimentation. |
