Evaluation of PET and PP Geotextile Reinforced Embankment on Soft Soil

AbstractParametric study is carried out to investigate the applicability of limit equilibrium method for analyzing reinforced embankment on soft soil with the use of GEO5 software in this paper. The effect of vertical spacing of geotextile layers, slope inclination, and tensile strength of PET (Polyester) and PP (Polypropylene) geotextile on the behavior of reinforced flyash+clay embankment on soft clay is determined. Results divulge that use of full length of geotextile covering whole width of embankment can increase factor of safety at stiffer slope inclination. Decreasing the slope and vertical spacing can also give safer design. Reinforced embankment with PET geotextile can also gives safer design compared to PP geotextile when considering creep phenomenon. here and insert a concise and factual abstract of this paper
