STABILIZATION OF SOIL BY USING GEOGRIDS

Stabilization is the main aim to reduce the bearing capacity of soil by using coated yarn geogrid. The supporting power of a soil or rock is referred to as its bearing capacity. Reinforced earth is a composite material a combination of soil and reinforcement suitably placed in layers to resist tensile stresses. In case of soft soils geogrid is one which redistributes the stresses internally with locally available backfill materials. Ground improvement technique using geosynthetic material i.e.geogrid is done below foundation. Using this technique; we can improve stability of available soil and increase the load bearing capacity. With this it also controls the earthquake vibrating forces. Reinforcement of soil to improve the ground (weak soil)using a polymeric geosynthetic material i.e. coated yarn geogrid is applied. This can also be implemented to many such weak places as road railway ballast airways slopes tunnels etc. in various ways. Stabilization is unavoidable for the purpose of highway and runway construction stabilization denotes improvement in both strength and durability which are related to performance.
