ABSTRACT
In addition to the traditional soil conditions under which ground improvement is often implemented, as described in Chapter 8 (e.g., loose, coarse-grained soils; soft, fine-grained soils; or loose, non-engineered fills), there are a number of special natural geologic conditions that produce problematic soil deposits and may require treatment. These include:
Highly compressible organic soils
Liquefiable coarse-grained soils
Collapsible soils
Expansive soils
Highly sensitive “quick” clays
Dispersive soils
Corrosive soils
High-sulfate soils
Unusual or special soil conditions
