Explain Factors affecting effective stress,
The pressure transmitted through grain to grain at the contact point through a soil mass is termed as intergranular or effective pressure. It is known as effective pressure since this pressure is responsible for the decrease in the void ratio or increase in the frictional resistance of soil mass.
If the pores of a soil mass are filled with water and if a pressure induced into the pore water tries to separate the grains, the pressure is termed as pore water pressure or neutral stress. The effect of this pressure is to increase the volume of decrease the frictional resistance of the soil mass.
Factors affecting effective stress:
1. Fluctuation on water table.
2. Hydrostatic condition.
3. Surcharge load.
4. Soil saturated by capillary action.
5. Seepage condition.
6. Quick sand condition.
