Abstract: This paper discusses the result of study conducted on rigid inclusions in black cotton soil. Black cotton soils are problematic soils. These soil swells on addition of water and shrinks on loss of moisture. Due to this buildings constructed in black cotton soil cause structural distress by differential settlement. Therefore rigid inclusions are adopted for improvement of these soils. Rigid inclusion is a ground improvement technique utilized in black cotton soil to improve the bearing capacity of the soil. It reduces the largest settlement by transferring the vertical load of the upper structure to the underlying load bearing stratum in which the piles are installed. A comparison between the virgin clay and rigid inclusion were also studied, in order to find the increment of load carrying capacity. The main objective of this paper is to investigate the characteristics, testing of rigid inclusion piles with one, two three number of piles and benefits in using black cotton soil. The experimental investigation of piles indicated that the required performance of the rigid inclusions is achievable.
