    • 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 ...

    • Energy transfer ratio for hydraulic pile driving hammers 

      Flynn, Kevin N.; McCabe, Bryan A. (NUI Galway, 2016-08-29)
      The ability of hydraulic pile driving hammers to overcome energy losses during freefall enables a greater proportion of the impact energy to be transferred to the pile in comparison to diesel hammers. This percentage, ...

    • Numerical modelling of the improvements to primary and creep settlements offered by granular columns 

      McCabe, Bryan; Sexton, Brian (Springer-Verlag, 2013)
      Analytical vibro-replacement design approaches typically quantify the settlement reduction using a dimensionless settlement improvement factor, defined as the ratio of the settlements without and with treatment. Most ...

    • Pile group settlement estimation: suitability of nonlinear interaction factors 

      McCabe, Bryan A.; Sheil, Brian B. (American Society of Civil Engineers, 2015-06)
      In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ...

    • A review of field performance of stone columns on soft soils 

      McCabe, Bryan (2009-12)
      The behaviour of stone columns has yet to be captured fully by analytical and numerical techniques, and predicting column behaviour in soft cohesive soils brings specific challenges. This paper provides a comprehensive ...

    • 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 ...
