Recent Study on the Behaviour of CFG Pile, DM (Deep Mixing) Column and Stone Columns Ground Improvement Technology
Journal Title: GRD Journal for Engineering - Year 2019, Vol 4, Issue 0
Abstract
In recent years, in ground improvement technique, such as deep mixing (DM) column, Stone Colum (SC), vibro-concrete columns, geosynthetic-reinforced embedded stone columns and CFG Pile, have been more and more used to support superstructures and embankments when they are constructed on expansive soil. Now a day’s new improved technology has emerged, along with different concrete columns, Pile, and composite foundations. New technologies have been combined with other ordinary technologies. It is give a better result, work effective and economical solutions. Thought, the composite columns / CFG pile with the composite technologies can be presented difficulty geotechnical problems in design and construction. This paper summary different types of ground improvement technologies and their application, installation and function addresses design issues, and reviews recent research and development related to the CFG piles to improve soft foundations, including failure modes, load transfer mechanisms, bearing capacity, settlement, consolidation, and stability. Several theoretical solutions have been proposed for the rate of consolidation of column-reinforced soft foundations. Different failure modes should be evaluated for the stability of column-supported embankments. Limit equilibrium methods based on shear failure overestimate the factors of safety of embankments on rigid or semi-rigid columns in soft soil. CFG pile, DM, and Stone Column are with the proposed on the principle of optimal design under a flexible load.
