     a number of triaxial tests were conducted for evaluation of randomly distributed fiber reinforcement effects on the behavior of cemented sand. cemented samples were prepared by addition of portland cement up to 3% by weight and were cured for about seven days after mixture. polypropylene fibers with a length of 12 mm were added and mixed in three different weight percentages of 0%, 0.5%, 1%. specimens were compacted in relative densities of 50% and 70%. consolidated drained compression triaxial tests were performed under confinements of 100, 300 and 500 kpa. tests results indicated that addition of polypropylene fiber to cemented sandy soils increases peak and residual strength. however, ultimate dilation decreases with enhancement of fiber content in cemented soil.
