  Clayey minerals are considered as the most important factor causing soils swelling, especially fine-grained soils. This phenomenon also causes the destruction of soil structure and texture and in the water vicinity makes damage to surrounding structures. Therefore, identifying and improving the condition of such soils can be very useful. For this purpose, standard laboratory methods have been proposed to evaluate the swelling potential of clayey soils. In this study attempted to use these laboratory methods to evaluate the clayey soils’ physicochemical characteristics and swelling potential form Ajabshir, East-azerbaijan province, NW of Iran. In this regard, the field survey, sampling and laboratory tests (such as physical, chemical and mechanical) conducted on 30 specimens were taken in Ajabshir. The soils samples are classified by United States Department of Agriculture (USDA) classification to identify the clay minerals classes for Ajabshir’s soil. Also, the indirect swelling potential evaluation was applied for providing the swellability condition of the studied soils. تفاصيل المقالة

  Study on clayey soil behavior under loading condition can help to understand the time-dependent creep phenomenon. The numerical and experimental procedures used by different scholars. The presented study used the numerical models to assessment of the clayey soil behavior regarding the creep. To this end, finite element method by Plaxis program was used for estimate the deformation and displacements analysis of clayey soils under creep event. According to the results, it has indicated the stress-strain-time behavior of unconsolidated soils under one-dimensional consolidation which it can be seen that the stress-strain applied during different time stages has different effects on the amount of creep. But the general nature of creepiness in unconfined soils is the same and one-way. This factor indicates the amount of all-out forces and residual stresses to improve the creep occurrence conditions. By plotting the axial stress-strain curve against the time logarithm, it can be stated that axial strains are the main cause of creep rupture in unreinforced soils. تفاصيل المقالة
