A STUDY ON SETTLEMENT BEHAVIOR OF SANDY SOIL REINFORCED WITH STEEL FIBER

Abstract

In this technical study deliberate about the load settlement response from plate (circular) load test put through on a 65cm diameter and 50cm height circular tank fill from compacted sandy soil mix with different percentage of steel fiber for a particular depth ratio and without reinforcement. The plate load test on the reinforced soil was performed at different pressures and show detectable strong response than compare the same test on non-reinforced soil. By the help of plate load test we can analyze the bearing capacity ratio of soil due to the steel fiber mix in soil .The load settlement curves for sandy soil reinforced with steel fiber in different quantity (0.25%, 0.5%, 0.75%, 1%), as well as on the same soil without the reinforcement have been produced. By comparing the load settlement curves, it is clearly observed that fiber reinforcement improved the behavior of the compacted soil and that bearing capacity ratio increasing with increase the percentage of steel fiber. Here one thing also observed that how bearing capacity ratio changes with H/D ratio. Where H=height of reinforced zone from plate level and D=Diameter of plate.
