Experimental investigation on stone column using waste materials

Abstract

Among various ground improvement technique, soft soil reinforcement by stone column is one of the most common and convenient method with numerous benefits including increased bearing capacity and consolidation reduced post construction settlement and lateral movement and improved slope stability and liquefaction control ,among others. They are mainly used for stabilization soft soil such as soft clay, silts, and silty sands. The stone column consist of compacted gavel (debris) and waste plastic bottle casing to reduce the clogging of material within the gap between debris particles. This article present installation methods, design and failure modes of stone column.
