For each footing, considering different time (t) for consolidation the settlement is calculated using following equations: where, is the time factor, is the coefficient of consolidation = 3 x 10-5 m2/min,
t is time in days.
For different t values calculate values. From values calculate the U %( percentage of consolidation) using following equations: for < 0.2 and, for > 0.2.
Get the settlement value as, S = x (U%/100)
