... length over diameter, L/D = 3.75, was installed in fully saturated dense Ottawa F-65 sand of target relative density D_r = 75%. The key aspects of the centrifuge modelling campaign, including: (i) construction of the monopile model including internal strain gauges...

... changes during the dynamic faulting. Overall, differences in the observed rupture propagation due to the vertical accelerations are demonstrated in two identically prepared dry sand models, highlighting an often-ignored rate effect in this complex process. Figure 4(a) illustrates how the data obtained...

... popularity, optimisation of the current design models can still be made. To address fundamental understanding of modelling effects in centrifuge testing of laterally loaded monopiles in sand, a large coordinated centrifuge-testing programme across nine different centrifuge centres worldwide has been...

..., its relationship with pile–soil relative stiffness (E_e/G*) remains under-explored. This study presents centrifuge experiments on nine steel tubular piles subjected to monotonic loading with unload–reload cycles in drained sand. All piles share the same diameter-embedded depth ratio...

... the results of CPTs carried out on a large flexible CC in a very loose and a medium-dense fine quartz sand. TPS were placed on the walls of the CC, allowing the measurement of horizontal stresses and their spatial distribution in all test phases: sample formation, lateral and cavity cell filling, piston...

... investigated for two methods of installation: impact driven at 100g, and monotonically jacked at 1g into saturated dense sand. The results highlighted two main features. (a) The effect of impact driving was pronounced for small amplitudes of horizontal loading. With regard...

..., there remains a paucity of engineering models to predict soil behaviour in different conditions. This paper presents the investigation of sand particle movement during RDC with a three-sided compactor using a 1:10 scale model in the laboratory. Settlements at different depths and cone tip resistance were...

... to investigate the load–penetration response and the soil flow mechanism in sand around the cutting edge of a circular open caisson. Full- and half-open caisson tests have been conducted considering different tapered angles of the cutting edge. The load–penetration response is investigated using the full-open...

... 2T, and it behaves as a long elastic pile in the case of the embedment depth of the pile being greater than 4T (Broms, 1964). The proposed values for n_h are 13 500, 6000 and 1900 kN/m³ for dense, medium dense and loose sands, respectively (Terzaghi, 1955...

... displacement with three different frequencies Testing soil used in this laboratory work is sub-angular fine Toyoura sand, and its index properties are given in Table 2 . Since the ratio of pile model diameter to grain-size diameter (B/d_{50) is about 83·33, which is comfortably greater than}...

...José Antonio Schiavon, Eng, MSc; Cristina de Hollanda Cavalcanti Tsuha, Eng, MSc, DSc; Luc Thorel, Ing, HDR, PhD Centrifuge modelling is an advantageous technique to simulate the behaviour of helical anchors in sand. The uplift capacity of a single-helix anchor is the sum of the helix bearing...

...Jelke Dijkstra; Christophe Gaudin; David J. White To investigate the differences in failure mechanisms beneath vertically loaded shallow foundations on silica and carbonate sands by way of particle image velocimetry analysis, 1g and centrifuge model tests have been performed. A comparison...
