8. SECONDARY CONSOLIDATION SETTLEMENT This is also called Secondary compression (Creep). “It is the change in volume of a fine grained soil due to rearrangement of soil particles (fabric) at constant effective stress”. The rate of secondary consolidation is very slow when compared with primary consolidation.

10. Flow chart for calculation primary consolidation settlement Data: soil characteristic( ,Cc,Cs,  c,e0) soil layers load of upper structure If clay layer is more than 2 m Divide layer in to some thick layers. Define the reference point for every layer Calculate overburden pressure from soil surface to the reference points

11. Calculate applied load from foundation base (  ) To reference points Summation settlement of every layers
