| Abstract | ||
| This study aims to find Geotechnical properties for soil in the Dijlah Area, (7) samples were taken from wells located in the area, according to the size analysis and the plasticity limits tests of that most soils are Silty soil of inorganic low plasticity of the type (ML) and the other sample (CL -ML). The results of chemical analysis showed that the percentage of gypsum ranged between (0.30% - 40.65%) and (T.D.S.) ranged between (56.14%-0.90%) that the high rates cause geometric problems on buildings and structures, While the proportion of organic matter (0.30% -0.95%) and pH values between (7.80–7.9), a somewhat acceptable values. The values of the moisture content of the soils ranged from (0.5% -3.0%) and the presence of gypsum and a collection of sample in the month of September clear effect on those values and may impact adversely on the Voids ratio and compression index, and cause in reducing the values of Cohesion and Internal Friction angle of the soil, Compression index values shown the high compressibility of soil, and the values of the Swelling index indication that the Swelling ratio is low. Soil was evaluated according to the values of the study area (O.C.R.) As excessive consolidation soil . Results showed that the X-ray diffraction test of non-clay minerals are predominant (Calcite, quartz, feldspar) and either clay minerals are (Montmorillonite, Illte, Kaolinite and Palygoroskite ( . | ||
