1.Fiber reinforcement has been utilized for soil stabilization. How does it contribute to stabilization? Discuss the utilization of natural and synthetic fibers.
2.A research study found out that stabilized soils in field often have lower strengths than those prepared in the laboratory. Comment on main reasons.
3.Write down (draw if necessary) the typical failure modes of deep mixed columns under vertical loads and embankment loads?
4.To increase the ultimate bearing capacity of a soft foundation at the base of an embankment, geosynthetic reinforcement can be used? Explain how this is possible?
