SOIL SETTLEMENT: PART 5 - SECONDARY CONSOLIDATION


THEORY

After the soil completes primary consolidation, the settlement continues by changing of physical structures of the soil fabric. This is so-called Secondary Consolidation or Creep.


The method to predict creep is not reliable and specific to soil types. A method suggested in Das (2002) can be used to compute secondary consolidation from t1 --> t2 after the end of the primary consolidation.

The general magnitude of

for various natural deposits are as follows:


OC Clays < 0.001

NC Clays are between 0.005 and 0.03

Organic Soil is 0.04 or more (***)
