Abstract
Identification of Expansive Soils and Ground Improvement Methods
Swelling problems generally occur in soils containing montmorillonit group clay minerals which
are often present in semi arid regions. Swelling soils may cause considerable financial loss due to damages of
one or two storey light structures, pipelines, roads, airports, retaining or garden walsl etc. Through early
determination of swelling behavior of soils of this type and factors affecting it, possible damages can be
decreased or prevented. There are numerous studies focusing on the measurement of swelling properties of
such soils, most of which use the conventional one-dimensional consolidation test that measures the swelling
pressure indirectly. In this study, the swelling of soils, identification are described in general terms and
methods of improvement are discussed. It was considered that the study useful for the researchers and
practitioners who study on the swelling soils.
