    • Appraising stone column settlement prediction methods using finite element analyses 

      Sexton, Brian G.; McCabe, Bryan A.; Castro, Jorge (Springer Verlag, 2014-09-26)
      Numerous approaches exist for the prediction of the settlement improvement offered by the vibro-replacement technique in weak or marginal soil deposits. The majority of the settlement prediction methods are based on the ...

    • Creep improvement factors for vibro-replacement design 

      Sexton, Brian G.; Sivakumar, Vinayagamoothy; McCabe, Bryan A. (ICE Publishing, 2017-02)
      Although the vibro-replacement stone column technique is being deployed increasingly in soft cohesive soil deposits in which creep settlements may be significant/dominant, the majority of existing stone column settlement ...

    • Heave-ho! A laboratory model of an underfloor environment incorporating pyritiferous fill 

      McKeon, E.P.; McCabe, Bryan A.; Sexton, Brian G.; Cavalcante, M.; Ibanez-Valle, J.L.; O'Connell, A.M. (NUI Galway, 2016)
      Damage to domestic dwellings in the greater Dublin area of Ireland caused by the expansion of underfloor fill material containing pyrite has become a high-profile national problem in recent years. In this paper, a novel ...

    • Modelling stone column installation in an elasto-viscoplastic soil 

      McCabe, Bryan A.; Sexton, Brian G. (Taylor & Francis, 2014-12-31)
      The majority of numerical studies investigating stone column performance have used “wished-in-place” columns (no installation effects) in conjunction with elastoplastic soil models (no viscous effects). In the first part ...

    • Stone column effectiveness in soils with creep: a numerical study 

      Sexton, Brian G.; McCabe, Bryan A. (Taylor & Francis, 2016-03-16)
      While it is well established that vibro stone columns reduce primary settlement and improve bearing capacity, their effect on creep compression has largely been overlooked to date. However, with increasing pressure to ...

    • Stone column settlement performance in structured anisotropic clays: the influence of creep 

      Sexton, Brian G.; McCabe, Bryan A.; Karstunen, Minna; Sivasithamparam, Nallathamby (Elsevier, 2016-07-15)
      The recently developed elasto-viscoplastic Creep-SCLAY1S model has been used in conjunction with PLAXIS 2D to investigate the effectiveness of vibro-replacement in a creep-prone clay. The Creep-SCLAY1S model accounts for ...
