Review on Encased Granular Stone Columns with Reinforced Clay System Using Geosynthetics

Abstract

In most parts of the world, problems related to soft soil are major challenges for geotechnical engineers. Stone columns have been used as an effective technique for improving the engineering behaviour of weak foundation. This review article is based on the findings related to reinforced stone columns used for ground improvement. Different types of geosynthetics are used & caused an improvement in settlement behaviour. The effect of various parameters such as diameter and depth of stone columns also considered. Other prime concern was the recent advancement of encasing of columns with geosynthetic products to enhance their performance under load bearing criteria and the foundation settlement. This paper contains fibrous details related to experimental, analysis and design studies on the aspect of encased granular columns that have been published in the last decade.
