ALTERATION OF SOIL BEHAVIOUR BY THE INCLUSION OF MATERIALS WITH DIFFERENT PROPERTIES

Two types of internal soil strain controlled inclusion systems are identified: tensile and compressive strain inclusion systems. These are characterised by inclusion orientation along the directions of principal strains in the soil without inclusions under the same stress conditions. The load transfer mechanism is shown to be dependent upon the inclusion possessing adequate friction/adhesion, and measurement of this can be achieved if thin layers of confined soil are in contact with the inclusions during a shear box pullout test. The differences between the influence of relatively extensible and inextensible inclusions are identified and found to be significant in terms of the overall load-deformation behavior of the soil inclusion system. It is noted that the orientation and location of the inclusions in soils is of vital importance to their operational efficiency. The deformation mechanism usually assumed in the analysis of soil alone may be greatly modified by the presence and type of inclusion. The identification of the operating mechanisms must therefore form an important part of any research and development program in this field. Earlier studies indicating that non-woven fabric inclusions had a strengthening effect has been shown to be valid so long as they are placed in the appropriate orientation and location.
