The main objective of this study is to determine the appropriateness unsaturated gypseous soil as a subgrade layer for carrying foundations. A comprehensive laboratory testing program was implemented investigate geotechnical characteristics and behavior soil. Tests that are physical included specific gravity, classification tests, relative density, Proctor compactions, single double oedometer c...

This study aims to increase the bearing capacity of soil by using geosynthetics in a single, double, or triple distribution pattern. The gypseous samples were brought from site near Sawa Lake Al-Muthanna Governorate with gypsum content about (37%), Soil-Model apparatus dimensions (60 × 60 50) cm proposed square footing (10 10) are used experimental program this study. To achieve goal, series (4...

Bearing capacity of soil is an important factor in designing circular footing. It directly related to foundation dimensions and consequently its performance. The calculations for obtaining the bearing a needs many varying parameters, example type, depth foundation, unit weight soil, etc. In this work, comparison between values footing on gypseous before after improvement determined by two diffe...

Existence of these soils, sometimes with high gypsum content, caused difficult problems to the buildings and strategic projects due dissolution leaching by action waterflow through soil mass. In this research, a new technique is adopted investigate performance replacement geosynthetic reinforcement materials improve gypseous behavior experimential set up manufactured loaclally specially for wor...

This study investigates the stabilizing effects of Halloysite nanotubes on geotechnical features gypseous soil as a subgrade. The that was utilized for this collected from Ayn al-Tamr in Karbala City, southwest Iraq, having an average gypsum 30% and designated (SP) by (USCS). As percentage dry unit weight soil, mixed with small amount nanomaterial (Halloysite nanotubes). A set physical chemical...

An extensive program of laboratory testing was conducted on ring footing rested gypseous soil brought from the north Iraq (Salah El-Deen governorate) with a gypsum content 59%. There are limited researches available, and even fewer have been done experimentally to understand how footings behave; almost all previous works only concern behavior under vertical loads, Moreover, relatively few studi...
