Abstract: This project work presents a series of uplift test is conducted in laboratory, using circular anchor plate of diameter 100mm embedded in sand, cement stabilized sand and fiber reinforced cement stabilized sand fill of various H/D ratio (1, 1.5 and 2). The test was conducted using model tank of diameter 500mm and height 500mm in universal testing machine. The uplift load was finding out by plotting load versus displacement curve of above fill material at various depths. The ultimate load carrying capacity of the fill materials is considered as uplift load. In this study the experimental result gave a clear indication of load carrying capacity, which was increased with the addition cement (4% of sand) and fibers (0.5% of sand) as reinforcement to the sand fill. In this work we used sand as fill material, as we all know sand is good in friction and non cohesive material. Using cement as binding material and polyester fibers as reinforcement to the sand fill. From the results it was clearly indication that increases in thickness of fill material which increases in the uplift load carrying capacity.
