GROUND IMPROVEMENT TECHNIQUES1AbstractThe fast urbanization and growth of population have caused the creation of infrastructure like railways, building, highways, etc. has minimized the availability of land. The engineers are left with a choice of using various type of soils in order to improve the strength by using the techniques of ground improvement for the activities of construction. The main motive of these techniques is to maximize the bearing capacity and minimize the settlement of soil. Group improvement is attained by using the glass, polymers, fibers, etc. Further, the report will explain the various types of ground improvement techniques with its applications. Then, the various types of soils will be given which will help in understanding the soil and their nature. Then the table of finding will be given which will help in understanding the type of soil which is required for the particular technique and the cost which will incur in implementing.

GROUND IMPROVEMENT TECHNIQUES3Introduction Nowadays, the industrial, cultural and economic growth of a country relies on the system of its transportation. The railways and highways help in providing maximum services to the customers.It has been observed that there is a scarcity of land because of the infrastructure’s development like buildings. As a result, the engineers are restricted to use weak and inferior soil for the process of construction. The various techniques of ground improvement are becoming very important for the projects of construction. This technique helps in increasing the soil’s strength and helps in reducing compressibility (Bitir et al, 2014). The soils which are expansive and collapsible are difficult to use because of their behavior of shrinkage and swelling action. The techniques of ground improvement help the construction easy on soft and organic soils, sanitary landfills, deposits of karst, etc. Further, the report contains the modern and important techniques of ground improvement with their applications.Ground Improvement Techniques The various techniques of ground improvement which are used nowadays are as follows (Patra, N. R., 2014):1.Mechanical Stabilization This technique helps in increasing the density of soil by using the mechanical force in the shape of vibratory rollers, static, plate vibrators, etc. in order to gain the compaction. Compaction can be done properly if the material of soil fill is graded properly. Further, it will be categorized by a coefficient of high uniformity Cu>15, a coefficient of curvature Cc within the range of 1 and 3 can be easily compacted to the high density with the help of tampers, rollers, and other tools.
