Perhaps the most technical chapter involves calculating total and differential heave. Chen outlines the method of summing the swell of discrete layers within the active zone.
The primary culprit behind extreme soil expansion. It has a structural molecular arrangement that allows water molecules to easily enter and expand the space between layers. Illite: Exhibits moderate shrink-swell potential. foundations on expansive soils chen pdf
These cyclical volume changes are responsible for an estimated $10 billion in damages annually in the United States alone. 2. Key Concepts from F.H. Chen's Work It has a structural molecular arrangement that allows

To mitigate the risks associated with building on expansive soils, engineers and builders can employ a range of design and construction strategies, including:
: Swelling soil can apply significant horizontal pressure against foundation walls. Key Identification Tests : Chen emphasizes the Swell Pressure Test
