If the water table rises upto ground surface, then the___________________?
  • (A)  effective stress is reduced due to decrease in total stress only but pore water pressure does not change
  • (B)  effective stress is reduced due to increase in pore water pressure only but total stress does not change
  • (C)  total stress is reduced due to increase in pore water pressure only but effec-tive stress does not change
  • (D)  total stress is increased due to de-crease in pore water pressure but effective stress does not change
Rise of water table above the ground surface causes________________?
  • (A)  equal increase in pore water pressure and total stress
  • (B)  equal decrease in pore water pressure and total stress
  • (C)  increase in pore water pressure but decrease in total stress
  • (D)  decrease in pore water pressure but increase in total stress
Quick sand is a________________?
  • (A)  type of sand
  • (B)  flow condition occurring in cohesive soils
  • (C)  flow condition occurring in cohesionless soils
  • (D)  flow condition occurring in both cohesive and cohesionless soils
