Abstract
Gypseous soil characteristics were studied types many researchers, but
the bearing capacity of sandy gypseous soil with different preparing of the soil
models were tested in dry condition under static and cyclic loads in this study, three
types of gypseous soils are prepared (artificial, gypsified and natural gypseous
soils). The laboratory tests were needed to evaluate geotechnical soil properties.
The main objective of this study is testing of the soil models in dry condition for
measuring earth pressures with displacements of the soil models under monotonic
and repeated loads within relatively large manufactured physical model. The
results found that the natural and gypsified soils have displacements of about (1 to
2 cm) and the pressures of earth reaches to about (500 – 550 kPa) and the artificial
gypsified soil reaches to (600 - 650 kPa) and the displacement of about (1 cm). SO3
content tested for the soil samples reaches to about (11.7 %) for gypsified and
natural soils while reaches about (24.5 %) for artificial gypseous soil.
