Uplift Pressure Head

Uplift pressu...

Question

Uplift pressures at points A and B shown in figure are 1.575 and 2.420 m respectively. If the sheet pile is at the downstream end of the floor, the uplift pressure at C is ________ m.

1.425

Solution

The correct option is A 1.425
$ϕ_{c} = 3 - ϕ_{A}$

$= 3 - 1.575$

$= 1.425 m$
