A STUDY OF BEHAVIOUR ON STONE COLUMN IN HOMOGENOUS SOIL S.Sandhya rani Post graduate student , civil engineering department, K.S.R.M college of engineering , kadapa. P.Suresh Praveen Kumar Assistant professor , civil engineering department , K.S.R.M college of engineering , kadapa. Abstract: In the modern civilized world ground improvement technique is a great concern to the geotechnical engineers. Stone columns are found effective, feasible and economical to improve the homogenous. Stone columns increase the unit weight and the bearing capacity of soil. It can densify the surrounding soil during construction. The improvement of a soil by stone columns is due to different sizes of aggregate…show more content…
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. At present a variety of soil improvement techniques are available for making soil to bear any type of structure on it and also for mitigation of seismic hazards. To improve the strength of the soils, especially in case clay, installation of stone column are found as best methods among all type of techniques. The various techniques used to improve the engineering property of soil are given…show more content…
The concept of soil improvement by reinforcing it with tension resistant elements in various forms has received the attention. This reinforcement can be provided in Vertical as well as in horizontal direction. Stone columns have been used to a large extend for several applications. Stone columns essentially increase the bearing Capacity of cohesive soils. Soils deposits can be improved by the installation of dense columns of gravel known as stone columns. They may be used in both fine and coarse grained soils. In fine-grained soils, stone columns are used to increase the shear strength beneath structures and embankments by accelerating consolidation and introducing columns of stronger material. The stone columns derive their load capacity from the confinement offered by the surrounding soil.In very soft soils this lateral confinement may not be adequate and the formation of the stone column itself may be doubtful. Wrapping the individual stone columns with suitable geosynthetic is one of the ideal forms of improving the performance of stone columns. Stone Columns provide an economical method of ground improvement and act as reinforcement to the ground into which they are
