Utilisation of plants for the soil stability and shear strength increase is studied by bountiful researchers across the globe, it’s a proven fact that soil roots provide an additional cohesion which increases the shear strength of soil and also helps in stabilizing natural slopes. But very few studies had focused on increase of bearing capacity by the usage of plant roots, in this study author had studied the bearing capacity and shear strength increase for various plants that can be used in soil bioengineering which is a potential tool for slope stability. Various plants were grown in pot culture in landslide affected soil collected from Nilgris District and the strength variation during the course of plant growth is studied. It is also found that not many standard test procedures are available for studying the real contribution of plant roots in soil stabilization, authors had utilized the North Dakota cone study for bearing capacity calculation which is a special case test used widely. It is found that plant roots not only provide additional cohesion for stabilizing the soil but also helps in increasing various other geotechnical characteristics on positive side. © 2015 CAFET-INNOVA TECHNICAL SOCIETY.
