Electro-Osmotic Consolidation of Expansive/Weak Soils at Nilgiris Region

Abstract

The Mountainous region are proven to landslides each and every year around the globe. It causes huge loss in revenue and also destructs the life of a common man. It is mainly due to the soil present and also the destruction of the forest cover in that area which causes the landslides. To control it various methods are used and landslides are prevented all over the world. Here, The Electro-osmotic consolidation is a method, which is used and experimented and conducted in the highly landslide prone areas in Nilgiris. The present study investigates the type of area present and examine the soil properties before and after the consolidation process. The soil sample was collected and the properties were tested. The consolidation was done in the lab with the help of Graphite and Iron as the cathode and anode respectively with power supply of 5-7 V and the excess water is dispersed with the help of a weight. The soil properties were again checked and the results were satisfied with the reduction of water content and undisturbed organic matter. It is concluded that the soil consolidation was economical and induced sufficient strength.
