Gypseous Soil Engineering Properties In The Middle Euphrates Area.

      Аннотация: The study area occupies about (47.130 thousand km2) in the middle part of Iraq country which situated with in mesopotamain plain. This study includes the geotechnical evaluation of Gypsiferous soil in four governorates in the middle Euphrates of Iraq (Babylon, Kerbala, Al?Najaf and Al-Qadissiya) it was done by the result of testing of (34) bore hole. The results of the grain size analyses revealed that the soil in the study area are alluvial origin and it is non? homogeneous and it contains large ranges of the size of grains. The grain size distribution of the gypsiferous soils of study area shows the sands percentage to be higher than those of the silt , clay and gravel percentages; the gravel percentage ranges between (0%?46%), the sand percentage ranges between 8% ? 95%; the silt percentage range between 3% ? 68%; the clay percentage range between 0%? 76 %.
