Ground Improvement Techniques
“GROUND IMPROVEMENT TECHNIQUES”
1. ABSTRACT:
Ground improvement is the most imaginative field of geotechnical engineering. It is a field in which the engineer forces the ground to adopt the project's requirements, by altering the natural state of the soil, instead of having to alter the design in response to the ground's natural limitations. The results usually include saving in construction cost and reduction of implementation time. There are number of techniques available for improving the mechanical and engineering properties of the soil. However, each technique has some limitations and suit abilities to get maximum improvement in the soil conditions with minimum effort. Some of the important techniques are discussed in this paper. To improve the strength of the soils, especially in case of granular type of soils, COMPACTION METHODES are found as best methods among all type of techniques. Based on the mechanism applied for compacting the soil, it is sub divided into different methods like dynamic compaction, blasting, vibro techniques ...etc.These are briefly discussed in this paper. When there are some limitations encountered for applying the above technique, grouting techniques, stabilization of soil using different admixtures can be adopted effectively which can bring variations in the soil conditions. The various types of above techniques are briefly discussed in this paper. Finally, recent advancements in ground improving techniques using GEOTEXTILES, ELECTRIC TREATMENT METHODES are also briefly discussed in this paper. These techniques are widely used in these days.
