A critical review on the performance of column improved ground under shear and seismic loading
Abstract
This paper reviews the performance of conventional stone column improved ground under static shear conditions and seismic loading. The limitations of stone columns in resisting lateral spreading due to shear movements and ground motions are detailed from extensive literature review. Suggestions for improving the shear resistance of improved ground with alternatives to stone column are incorporated. The better performance of pervious concrete column as an alternative to stone column under static shear and seismic loading is also briefed.
