Foundations On Expansive Soils Chen Pdf Jun 2026

After weeks of hunting through university archives and interlibrary loan requests, I finally got my hands on a scanned copy of (the classic Elsevier edition).

The most reliable method for highly reactive clay. These extend deep into the ground to reach stable bedrock or non-expansive strata.

Expansive soils are highly plastic soils that contain minerals such as montmorillonite, which can absorb and release large amounts of water, leading to significant volume changes. These soils are commonly found in arid and semi-arid regions, where the climate is characterized by low rainfall and high evaporation rates. Expansive soils can be problematic for construction, as they can cause foundations to shift, crack, and even collapse.

Expansive soils, also known as swelling soils, are a type of soil that can cause significant damage to structures built on them. These soils have a high potential for swelling and shrinking, which can lead to uneven settlement, cracking, and even collapse of foundations. In this blog post, we will discuss the challenges of building foundations on expansive soils and provide an overview of the book "Foundations on Expansive Soils" by Chen, available in PDF format.

Chen, L.Y. (1988). Foundations on expansive soils. Journal of Geotechnical Engineering, 114(10), 1086-1104.

Standard thin slabs crack and tilt as the soil underneath moves irregularly. Dry Season (Shrinkage) Wet Season (Heave / Swelling)

Chen acknowledges that if the top 2 feet (0.6 m) of expansive soil is removed and replaced with granular fill (or lime-treated clay), heave can be reduced. However, he warns that lateral moisture migration from adjacent areas can still cause problems.

Swelling soil behind retaining structures exerts immense lateral pressure, causing walls to tilt, crack, or slide forward.
