Sandy Soils Improvement Techniques and Its Applications

Enhancing Soil Stability and Bearing Capacity through Ground Improvement Techniques

Abstract

In recent years rapid development of infrastructures in metro cities compounded with scarcity of useful land and compelled the engineers to improve the properties of soil to bear the load transferred by the infrastructure e.g Buildings, bridges, roadways railways etc. The engineering techniques of ground improvement are removal and replacement, pre-compression, vertical drains, in-situ densification, grouting, stabilization using admixtures and reinforcement. The purpose of these techniques to increase bearing capacity of soil and reduce the settlement to a considerable extent. The one of the method among ground improvement techniques is reinforcing the soil with materials like steel, stainless steel, aluminum, fibers, fiber glass, nylon, polyster, polyamides in the form of other strips or grids and Geotextiles. The Primary purpose of reinforcing a soil mass is to improve its stability, increasing its bearing capacity and reduce Settlements and Lateral deformations. Geotextiles and geomembranes, broadly speaking are synthetic fibres used to stabilize structures built on soil. The new widely accepted generic term for these non-natural materials is Geosynthetics.
