Collapsible soils are present in arid and semi-arid regions in an unsaturated state and are
considered to be one of the problematic soils that face engineering and geotechnical …

Gypsum is a soluble bonding substance that is one of the soil's problematic components in
Iraq's west. This component dissolves during the wetting process. The behavior of bonded …

This paper investigates the water volume changes in gypseous sand soils within the change
in matric suction and under different stress levels. The present research aims to examine …

This study examines the brittleness index and sensitivity ratio of two gypseous sand soils
under saturation conditions improved by nano-clay. The soil samples were obtained from …

A relevance between moisture content in a soil and suction is shown by the soil water
characteristics curve (SWCC). The recent paper focuses on the stress-dependent SWCC for …

The soil water characteristics curve (SWCC) demonstrates a link between soil moisture
content and suction. The SWCC is almost treated as an index parameter in unsaturated soil …

ABSTRACT Al-Najaf, one of Iraq's most important cities, is expected to grow in the coming
years. Many buildings located on the slopes of Al-Najaf, which is near the shrine of Imam Ali …

Due to the attraction of the hilly views and lack of flatland in some countries, there are needs
to the construction near the slopes. In evaluating slope stability, attention must be …

Gypsum is a soluble material, and it is one of the problematic components in the soil in the
west of Iraq. Al-Najaf is one of the governorates in Iraq which suffers from the gypsum …
