Chen, F. H. (1988). Foundations on expansive soils. [PDF document].
In 1988, Chen published a comprehensive study on the design of foundations on expansive soils. The research, which was later compiled into a PDF document, provided a detailed analysis of the behavior of expansive soils and proposed new design methods for foundations on these soils. Chen’s work built on earlier research and provided a more comprehensive understanding of the soil’s behavior. foundations on expansive soils chen 1988 pdf
Expansive soils are typically clay-rich soils that have a high cation exchange capacity. They are characterized by their ability to swell or shrink in response to changes in moisture content. When the soil is dry, it shrinks and becomes more dense. Conversely, when the soil is exposed to water, it swells and becomes less dense. This volume change can cause significant stress on structures built on the soil, leading to cracking, uneven settlement, and even collapse. Chen, F
