| Abstract | Expansive soil is defined as the soil that has potential to increase in volume under increasing water content. Seasonal and environmental changes can resultinmoisture content change of expansive soil and cause damages of structures founded on them. Upon expansion, the soil exerts an upward pressure on foundations. If this pressure is greater than the foundation pressure and the overburden pressure of the soil,then uplift or differential uplift occurs and could cause walls,beams and columns to crack. Consequently, assessing the swelling pressure is an important step in designing foundations on expansive soilsIn this study, swelling behavior of compacted residual soil is measuredby using oedometer device. The measurement is done by three different methodsincluding the swell-consolidation method, swell under applied stress method and the constant volume method.The soil compacted at different values of dry density and water content weremeasured and their relationsto the swelling potential of the soil wereinvestigated. It is concluded that swelling potential of soil is directly proportional to the dry density values and inversely proportional to the water content of the soil. The swell consolidation test method is good for measuring the swelling potential of the soil. The measurement under the applied stress test method results in both swelling and collapse potential of the soil. The constant volume method gives the relation of swelling pressure to the soil physical properties. |
