“…In their analysis, the installation of the sand pile was modelled as an expansion of a cylindrical cavity in the clay bed, thereby ignoring the effects of driving, withdrawal and re-driving of the casing. Some other simplified approaches have also been reported in the literature, such as removing and reactivating elements (Farias et al, 2005), or the adoption of a 'dummy material' numerical procedure (Guetif et al, 2007). None of these studies models the 'downward-propagating' expansion of the cavity during casing jack-in and 'upward-propagating' expansion during retraction and sand injection.…”

“…Detailed discussion on how to determine these parameters can be referred to corresponding references [13~15]. The values of the parameters, determined from the accumulated experiences on Toyoura sand [15,16], are provided in Table 1.…”

“…Farias et al (2005) also conducted FEM simulation of static sand pile installation using a sophisticated model. They found that compacted sand piles installation densiˆes the surrounding soil not only horizontally but also vertically to a depth ofˆve diameters from the pile tip.…”
