IMPROVEMENT OF LOAD BEARING CAPACITY OF BLACK COTTON SOIL BY USING STONE COLUMN AND GEOSYNTHETICS

Abstract

A Black cotton soil has low bearing capacity and high compressibility and more settlement. Black cotton soils are more reactive to seasonal moisture content so need to improve the soil properties and improving the load carrying capacity by providing geo textile discs at various depths and various diameter of stone column. Stone column diameter used are 2.5cm and 5 cm and reinforcement placed at depths of 0.25, 0.5, 0.75, 1.0 of the length respectively. For every settlement of 30mm ultimate load is determined.
