Abstract:
The swelling potential is the most important factor on engineering and agricultural design of foundations on fine-grained soils which it can be cause expansion problems for these structures. So, providing the suitable views of swelling condition can help to solid designs. The presented paper, tried to understand the clayey soil’s swelling potential related to Marageh city in East Azerbaijan Province, NW of Iran; by using comprehensive laboratory tests (concluded ۲۵ samples from ۱۰ different sampling location) which included physicochemical properties, USDA class of soil and clay mineralogical aspects. The experiment results was used by regression analysis for formulate the swelling based on laboratory indexes (i.e., water absorption, porosity, density, Gs, SO۴-, Cl-, pH, Casagrande limits, UCS, XRD and clay content). According to the analysis results, the studied soil’s (where classified as clay, clay loam and silty clay) swelling status is varied and located in moderate to high potential
