Effective-Stress
Briefly explain Quick sand Condition
Quicksand condition or boiling quicksand condition is a condition that generally occurs in the cohesionless soil, like fine gravel and sand, when, the effective stress is reduced due to the upward seepage flow of water. When the upward flow is increased, a stage is reached at which effective stress is reduced to zero. The condition so developed is known as quicksand condition. As sand boiling occurs, the bearing capacity and shear strength of the cohesionless soil decrease and the agitations of soil particles become apparent.
How Quicksand Condition Occurs?
Quicksand condition occurs when seepage pressure, which acts in the upward direction, overcomes the downward direction pressure due to submerged weight of soil, and the sand grains are forced apart. The result is that the soil has no capability to support a load.
