Question
The relationship between the specific gravity of sand () and the hydraulic gradient () to initiate quick condition in the sand layer having porosity of 30% is
Correct answer
(C) G = 1.43i + 1
Solution
The critical hydraulic gradient required to initiate quick condition is given by the formula:where is the specific gravity and is the void ratio.
The relationship between void ratio () and porosity () is:Given porosity , we have:Substituting into the formula for :Rearranging to solve for :Thus, the correct relationship is .
