CONSTRUCTION PROPERTIES OF FLOOD DEPOSITS IN THE DIWANIYAH RIVER

Abstract

Natural foundations of the buildings located in the middle Iraq region are represented by quaternary deposits that have been formed as residue of fine (clay and dusty) particles being transported by low-speed water flow. Density of clay soil is changeable within the following limits 1.38–1.47 g/cm3, and module of general deformation is equal to 1.6–1.9 МPа. In accordance with such characteristics foundation residues reach limit values at contact pressure of  80–100 kPa though design resistance of soil is within the range of  180–250 kPа. In the case of significant soil load transfer it is necessary to consider variants of deep foundation. In this connection while executing engineering and geological research it is recommended to drill some exploration wells at the depth of 40–60 м
