Stone column settlement performance in structured anisotropic clays: the influence of creep
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 ...
Modelling stone column installation in an elasto-viscoplastic soil
(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
(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 ...
Ground heave induced by installing stone columns in clay soils
(ICE Publishing, 2013-12)
Measurements of ground heave induced by installing stone columns in soft clay are presented in this paper. These measurements are likely to provide guidance to practitioners concerned about the possible impact of column ...
Appraising stone column settlement prediction methods using finite element analyses
(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 ...
