Ground Improvement Technique

Abstract

Ground Improvement Technique In a construction project, there are numerous foundation problems that are encountered during the execution phase. Soil in its natural form, at a construction site, is not always suitable to completely bear heavy structural loads. For such situations, the soil needs to be improved to enhance its bearing capacity and decrease the expected settlement. There are certain techniques for ground improvement which are often used to improve sub-soil properties in terms of their bearing capacity, shear strength, settlement characteristics, drainage, etc. These techniques have a wide range of applicability from coarse grained soils to fine grained soils. Depending upon the loading conditions and nature of soil, a suitable technique which is also economical needs to be adopted. This paper gives the overview and concept of recent major ground improvement techniques and discusses their practical applications.

Conclusion

Room for improvement in the traditional techniques has become difficult. Also, some methods such as thermal improvements are costlier whereas methods such as vertical drains require skilled labor. On the other hand waste disposal has also become a great problem for the policymakers. Therefore, researchers are now shifting towards utilization of waste products such as construction demolition wastes, pozzolanic materials, silica fume, etc. in the soil stabilization  processes. Many different researches have been carried out using different waste materials. Recently, different combinations of waste materials are being tested for soil stability and these types of waste products can provide better characteristics and are environmental friendly.
