摘要：It is due to rapid growth of population, fast urbanization and more development of infrastructures likebuildings, highways , railways and other structures in recent past years has resulted in reduction of availability of goodquality of land. Therefore engineers have no choice left except to use soft and weak soils around by improving theirstrength by means of suitable modern ground improvement techniques for construction activities. At present theavailable ground improvement techniques are replacement of soil, vertical drains, stone columns, vibro compaction ,dynamic compaction, soil reinforcement, vibro piers, in-situ densification, pre-loadings, grouting and stabilizationusing admixtures. The aim of these techniques are to increase the bearing capacity of soil and reduce the settlement.Ground improvement by reinforcing the soil is achieved by using fibers of steel, glass ,various polymers in the formof strips or grids and geosynthetics. Geosynthetics may be permeable or impermeable in nature depending oncomposition and its structure. The geosynthetics material can be used to perform different roles in differentapplications. It can be used as reinforcement, separation, filtration, protection , containment and confinement of soil toincrease its bearing capacity. Depending upon the requirement and site condition a Geocell reinforcement may also beused. This paper presents a thorough study on various available modern ground improvement techniques and theirapplications in civil engineering in present scenario. On the basis of long term performance results of various groundimprovement techniques and its analysis, an efficient design can be developed and a suitable method of groundimprovement technique may be adopted for a particular application.
