The suitability of soils for constructor in selected sites at Nasiriya City, South of Iraq

الملخص EN

Expansive soils are defined as those soils whose volume changes under the effect of wetting and drying cycles are these soils associated with the problems and failures that have been observed in construction field as reported from many parts of the world.

In this paper various geotechnical properties have been studied .The purpose of this study is to evaluate soils for suitable construction.

Four different sites were selected to evaluate some of geotechnical properties in some regions of Nasiriya city.

By studying grain size distribution, chemical tests, Atterbreg limits, Consistency index swelling potential, and consolidation parameters.

The present study provides typical ranges of some soil parameters.

The soil in the city of Nasiriya has a variation of engineering properties with depth.

The sites were selected from different areas to compare between the engineering properties.

The soil has low plasticity (LL < 50), and high swelling potential.

Some of the study areas contain a percent of sulphate, which has a negative effect on concrete structures.
