ABSTRACT: Problematic
soils usually cause considerable problems to engineering projects. As an
example, soil structure collapse caused by moisture increment or rising
underground water level results in huge settlements. This type of problematic
soil, named collapsible soil, can cause dramatic problems and should be amended
where exists. Today,
the use of different techniques for soil reinforcement and soil improvement is widely used to treat soil properties. One of these
methods is Deep Soil Mixing (DSM) method. This method becomes more important in the cases of studying and examining collapsible
soils. In this research, the settlement of amended collapsible soils, applying deep soil mixing method, is examined. The experiments show that soil
amendment using this method, well prevents the settlement of collapsible soils
giving rise to bearing capacity.
