تأثير دورات الترطيب و التجفيف على التغيرات الحجمية للترب الانتفاخية

Abstract EN

In this research, the wetting and drying cycles that expansive soils are exposed to will be studied, and the results will be compared with soils that underwent a One wetting cycle.

The results showed a decrease in the axial deformation of the soil with an increase in the number of cycles starting from the second cycle, but the relationship between the deformation and the logarithm of time showed the increase in the axial deformation with the increase in the number of cycles until a certain time, at this time the deformations change stops at most of the cycles, and the value of the void ratio taken at the end of wetting cycles is shown to decrease with the increase in the number of cycles, which means decreasing the sample voids volume at the end of wetting with cycles, which indicates the fatigue of the material as a result of exposure to the cycles.
