Immediate settlement sq --- 5.2 mm

Consolidation settlement

Divide clay layer into N = 5 sub-layers of thickness At =-—-= 0.6 m

For each layer i = 1.. N, the depth below base to the centre of each layer is At given by zi = (At x i) —— and the normalized foundation half breadth by B

mi =-. The influence factor Iq = Iq~(mi) can be found from Fadum's i 2zi qi '

chart. The change in vertical stress in each layer is A av = 4Iq Aqd and the i h settlement in each layer pc = m^ Actv At.O

Substituting values into the previous expressions gives:

settlement in each layer pc = m^ Actv At.O

Substituting values into the previous expressions gives:
