IMPROVEMENT OF STABILITY OF SLOPES AND REDUCING THE SEEPAGE USING GEOTEXTILE IN EARTHEN DAM

Abstract

Reinforcing the soil is now well established technique for geotechnical application across the world. This paper represents the application of Geotextiles in reinforcement and geomembrane for the stability of slopes and decreasing the seepage loss through the body of the earthen dam respectively. The dam section like slope designed by Kandi Area development organization Chandigarh has been considered to be reinforced with horizontal layers of geotextile and Factor of safety with and without reinforcement has been studied. Moreover, the parameters such as spacing and length of reinforcement are also varied. Inclined geomembrane is used on u/s face of the dam to reduce the seepage lose through the dam body. It was found that by providing geotextile and geomembrane as a reinforcement increases the factor of safety at the d/s and u/s slope with satisfactory results to reduce the seepage lose.
