Swelling of Black Cotton Soil Using Centrifuge Modeling

Abstract

Expansive soils, such as black‐cotton soils, create problems for structures built on them due to their high swelling and shrinkage characteristics. In the field, the magnitude of swelling depends on the soil thickness. Swelling experiments were conducted on black‐cotton soil in a geotechnical centrifuge and the results were compared with those obtained from the integration of the results of 1‐g swelling experiments under different surcharge stresses. The agreement between these results has been found to be close.
