Geotechnical Properties of Soil Slopes of the Great Musaiyab Project, Babylon, Middle of Iraq

Abstract

The research deals with the study of the geotechnical properties of the soil of the banks of the Great Musaiyab Project in the province of Babylon in central Iraq, as it includes the study of the physical, chemical, engineering, and mineral properties. The results of the physical tests showed that the grain size distribution of silt was higher than that of clay and sand at a rate of 36.91%, that of clay 30.9% and that of sand 31.06%, and the average of the maximum dry density values was 1.9125g/cm3. The average specific weight was 2.69, and the results of chemical tests showed that the percentage of carbonates (17.98%, percentage of gypsum 0.7075%, the percentage of sulfates 0.3282%, percentage of organic substances 2.7435%, and the percentage of total salts soluble 1.7193%. The results of the engineering tests indicated that the direct shear test showed that the cohesion value ranged between 0 and 50 KN/m2, the internal friction angle ranged between 7 and 37, and the unconfined pressure resistance ratio ranged between 3 and 48 KN/m2. While the results of the metal properties indicated using ray diffraction XRD, which showed the mineral content of the soil, as it consisted mainly of calcite, quartz, and feldspar, in addition to clay minerals.
