Strength Improvement of Soil by Encased Trench of Different Replacement Materials

One of the main problems that a developing country such as India faces is urban displacement. This leads to insufficient resources to meet therising demands for accommodation. Soft and very soft clay deposits are considered among the most challenging soil formations to build on,because they possess high compressibility and low shear strength properties. One of the best methods which can be done to improve thebearing capacity of a soil is by making a trench filled with granular material. The present study focuses on the effect of providing differentreplacement materials in the trench encapsulated with geotextile on settlement reduction. The present study focuses on the effect of providingdemolition waste materials (DWM) and mixture of sand and copper slag granules (CSG) as replacement materials in the trench encapsulatedwith jute and Non-woven geotextile. Footing over the encapsulated trench of demolition waste materials, mixture of sand and copper slaggranules showed an improvement in the load carrying capacity and the reduction in the settlement. For trench of demolition waste materialssettlement reduced by 45% using encapsulated trench than without using trench. For trench of mixture of sand and copper slag granulesSettlement reduced by 38.5% using encapsulated trench than without using trench
