A case study on various developments of soil reinforced embankment slope stability with natural fibre additives

Abstract

In this work, an attempt is made to study the influence of jute fibre reinforcement with the help of three case studies discussed here. The first case study described laboratory model testing and numerical analysis performed on a modelled slope that simulated an existent embankment that failed on many occasions following overnight heavy rainfall. The second case study discussed how vegetation may minimise the likelihood of soil separation and the velocity of surface run-off by decreasing surficial soil erosion. Jute geotextile (JGT) has an excellent hydrophilic characteristic that aids plant development, for this reason, it was used. The third case study developed a multi-fibre approach to traditional geotextiles to create an eco-sustainable product(s) with superior geotechnical qualities for improving the efficiency of earthen structures using soft revetments. The conclusion of these case studies expressed the novel objective for the improvement of embankments with stability analysis. This research also arose with the soil sample testing and the numerical modelling using Geo-studio. The slope model will consider being reinforced with the different rows of jute tassels on the embankment for enhanced stability and a factor of safety. Hence, the presence of jute fibre geotextile results in better performance in the stabilization of soil and also with the minimum value of deformation and maximum value of the factor of safety.
