... within the pile group was found to have a major impact on the mobilised pile resistance. The position, however, became less significant as the load level increased. Furthermore, insights were gained concerning the load distribution within piled rafts during consolidation. In addition to the time...

Webster, PhD; Oladipo Omotoso, PhD, PEng Oil sand fluid fine tailings in northern Alberta have very poor water-release characteristics and require many decades to fully consolidate under their own weight. Generally...

...Fauzan Sahdi; Christophe Gaudin; David J. White; Noel Boylan This technical note describes a simple methodology for reliably measuring the undrained strength of ultra-soft consolidating clay in the geotechnical centrifuge, using the T-bar penetrometer. This methodology relies on the T-bar...

... was to investigate the effect of lump size distribution on soil compressibility during self-weight consolidation. In addition, oedometer tests were carried out to investigate the response of double porosity soil to one dimensional loading with the attendant degradation in structure. Comparison with large centrifuge...

... to attack a simulated consolidated Kaolinite clay layer. The experiments were conducted using a geotechnical centrifuge and a compacted clay model corresponding to an equivalent prototype clay layer that was 2 metres thick according to conventional scaling laws. Pore pressure transducers located in the clay...

... conditions were adopted in the experiments: ‘tunnel drainage condition’ where the tunnel lining acts as a drainage boundary, and ‘bottom drainage condition’ in which one-dimensional consolidation of the clay takes place due to lowering of the ground water level. The test results are compared in view...

... testing. In both cases, physical modelling is shown to reveal limitations in analytical models. An approach for in situ determination of the consolidation coefficient, by means of variable rate penetration testing, is described. © Thomas Telford and ICE 2001 physical modelling numerical modelling...
