Foundations On Expansive Soils Chen Pdf Guide

Expansive soils, also known as swelling soils, are soils that exhibit significant volume changes in response to changes in moisture content. These soils can cause significant damage to structures built on them, particularly foundations. In this post, we will review the Chen method for designing foundations on expansive soils, as presented in Chen (1988).

Many foundation failures occur because engineers treat the soil as a semi-infinite half-space without acknowledging that moisture changes are rarely uniform with depth.
