A7: STUDY ON THE STRESS-STRAIN BEHAVIOUR AND SWELLING CHARACTERISTICS OF DISPERSIVE SOIL
Dispersive soils pose significant challenges in geotechnical engineering due to their unique characteristics. Using dispersive soils in structures may cause serious engineering problems ,if they are not identified and used appropriately. Standard soil testing methods are employed to assess the physical properties, mineral composition, and engineering properties of soil. Specialised tests are conducted to evaluate the dispersive nature of the soil, including the pinhole test and crumb test. This involves laboratory testing on samples of dispersive soil collected from different locations. The stress-strain behavior and swelling characteristics of dispersive soil are examined in order to gain a deeper understanding of its mechanical properties and its behavior under various conditions. The stress-strain behaviour is investigated by conducting unconfined compression tests under various percentages of additive, this gives insights into the strength and deformation characteristics of dispersive soil. Swelling characteristics of the dispersive soil are assessed by conducting free swell tests. This study contributes to the understanding of dispersive soil behavior and provides essential data for the design and construction of civil engineering projects in regions where dispersive soils are prevalent. The results can be used to develop appropriate engineering solutions and mitigate the challenges associated with dispersive soils, ultimately improving the safety and stability of infrastructure in dispersive soil prone areas.
