The Chen method involves the following key equations:

Dr. F. H. Chen was a distinguished geotechnical engineer and professor at California State University, Sacramento. His career was dedicated to understanding unsaturated soil mechanics. His book, "Foundations on Expansive Soils" (published by Elsevier Scientific Publishing Company, 1975, and later a 2nd edition by Elsevier in 1988), was revolutionary because it bridged the gap between laboratory soil science and practical foundation design. foundations on expansive soils chen pdf
