Study of stone column in expansive and non-expansive clay

Abstract

Stone column driving is a cost effective, environment friendly and easy ground improvement technique. Introduction of stone columns in soil generally increase the unit weight of soil and by doing so ultimately it improves the bearing capacity of soil. It also densify the surrounding soil during process of its driving. Population explosion, which cause scarcity of land having sufficient bearing capacity for the construction of building to provide shelter and services. The installation or driving of stone column in non-expansive clay and expansive clay improve bearing capacity and reduce settlement of clay, which provide suitable condition for the construction of foundation of structure. In this research work the main concern of study is to compare effect of stone column in non-epxansive clay and expansive clay. Further comparison between strength of full length stone column in both the soil is studied in this research work.
