Abstract
Stone column technique is an economical and environmentally friendly method used to improve the load settlement of problematic soils. Geosynthetics used for increasing bearing capacity and permeability of soil, reducing settlement of soil. Stone column with geotextile is placed horizontally and encapsulated in the soil and find the settlement done in by applying the load in the plate load test. The studiesshows that the settlement is lower for horizontally placed geotextile when compared to the settlement for encapsulated geotextile in the stone column. Improvement can be done by increasing the stiffness of the geotextile which increases the load bearing capacity of the soil. In the experimental programmed, we prove that the stone column with horizontally placed geotextile has high safe bearing capacity and low settlement. Geotextiles can be used in both vertical and horizontal applications to help solve drainage problems around the home and along the roads. For protection, geotextiles can be used to absorb stress and thus reduce or prevent damage and erosion in geotechnical structures. Stone column with Geosynthetic which ultimately increases the load bearing capacity of the stone column and prevents bulging.
