When does a quick sand condition is developed in soil?
Head causing upward flow is increased
This critical gradient is achieved when the hydraulic head causing upward flow is significantly increased. Head causing upward flow is increased: An increased head causing upward flow leads to a higher upward hydraulic gradient.
Important Questions from Seepage Analysis
Which one of the following equations correctly gives the relationship between the specific gravity of soil grains (G) and the hydraulic gradient (i) to initiate 'quick' condition in sand having a void ratio of 0.5?
In the graphical method of obtaining flow nets, if the lowest flow line confirms to the bottom boundary conditions, the flow net:
The hydraulic gradient between two adjacent equipotential lines is given by:
A soil has a discharge velocity of 6 × 10 -7 m/s and a void ratio of 0.5. What is its seepage velocity?
If the void ratio and discharge velocity for soil is 0.5 and 6 × 10-7 m/s respectively, what is the value of seepage velocity (m/s)?
