Degree Of Saturetion (as Per Consolidation & Settlement) Formula

Consolidation & Settlement As per permeability: 1. 2. 3. 4.

Mass of dry soil = (Mass of container + dry soil) – Mass of container Mass of water = (Mass of container + wet soil)-(Mass of container + dry soil) Water content = (Mass of water/Mass of dry soil) x 100 Degree of saturation =(Water content x Sp.gravity of soil)/Void Ratio

As per consolidation: 1. 2. 3. 4. 5.

Moisture content = (Mass of water/Dry mass of sample) x100 Dry unit mass = (Dry mass of sample/Volume of ring) Wet unit mass = (Wet mass of sample/Volume of ring) Final height of sample = (Initial height of sample-total change in height) Reduce height of solid = ( /Sp.gravity of solid x Area of ring x Mass density of water) 6. Void ratio = (Total changes in height /Reduce height of solid) 7. Degree of saturation = ( x Sp.gravity of soil)/Void ratio Unconfined Compression: 1. 2. 3. 4. 5.

Mass of specimen =( Mass of specimen +Mould)-Mass of mould Density of specimen = (Mass of specimen/Initial Volume of specimen) Water content = (Mass of crucible + Wet soil)/( Mass of crucible + Dry soil) Void ratio = [Sp.Gravity x (1+ mass of specimen) x Mass density of water)] Degree of saturation = {(Sp. Gravity x Mass of specimen)/Void ratio} x 100

Shrinkage factor: 1. 2. 3. 4.

Mass of water = (Mass of dish + wet soil pat) – (Mass of dish + Dry soil pat) Mass of dry soil pat = (Mass of dish + Dry soil pat) – Mass of empty shrinkage dish Initial water content = (Mass of water/Mass of empty shrinkage dish) x 100 Mass of mercury = (Mass of weighing dish +Mercury) – Mass of weighing empty dish 5. Volume of wet soil pat = (Mass of mercury/13.6) 6. Mass of mercury displaced = (Mass of weighing dish + Displaced mercury(by dry soil pit))-Mass of weighing empty dish 7. Dry soil pat = (Mass of mercury displaced/13.6)
