An experimental and theoretical comparison between static and dynamic torsional soil tests / M. D. Bolton in Géotechnique, Vol. 39 N°4 (Decembre 1989) 

Public ISBD [article]  in Géotechnique > Vol. 39 N°4 (Decembre 1989) . - pp. 585 –599 Titre : An experimental and theoretical comparison between static and dynamic torsional soil tests Type de document : texte imprimé Auteurs : M. D. Bolton, Auteur ; J. M. R. Wilson, Auteur Année de publication : 2007 Article en page(s) : pp. 585 –599 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Damping  Torsion  Stiffness  Resonant  column  tests  Soil  properties Résumé : The dynamic properties of dry Leighton Buzzard sand have been investigated using a resonant column test apparatus. These data are compared with very low frequency cyclic tests on identical specimens of sand. The comparison indicates that the properties of dry sand are independent of frequency. A simple one-dimensional model of kinematic hardening plasticity is used to predict the dynamic behaviour of the sand. The input parameters for this model are based on the results of static tests. These may be conducted on standard laboratory equipment with only minor modifications. The predictions are in good agreement with the measured data. In particular, the frequency response close to resonance was correctly shown to be asymmetric and the reduction in the resonant frequency with increasing strain amplitude was also correctly represented. The practical consequences of these findings are assessed with regard to soil testing procedures and dynamic analyses of foundations. Particular emphasis is placed on the dynamic analyses of the foundations for vibrating machinery and offshore gravity structures.

It can analyse the combined effects of higher strain rate and variation of strain rate across the soil mass on the undrained strength derived from pressuremeter tests. The results of a parametric study using this method indicate that the stress-strain curves derived from the pressuremeter curves differ from the true material stress-strain curves and that the undrained strength is overestimated.

Predicting the phenomenon of burying through gravity in purely cohesive sedimentary sea beds / J. Pastor in Géotechnique, Vol. 39 N°4 (Decembre 1989)

Pastor, Auteur ; S. Turgeman, Auteur ; C. Avallet, Auteur Année de publication : 2007 Article en page(s) : pp. 625 –639 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Finite  elements  Offshore  geotechnics  Analysis  Limit  state  design  Plasticity Résumé : The phenomenon of gravitational burying of solid bodies laid on a silty or clayey sedimentary sea bed is largely due to the plastic flow of the material composing this sea bed. Consequently it can be rationally quantified in the theoretical framework of limit analysis. In this study, the solid bodies are cylinders laid on their generatrix that are sufficiently long to justify the assumption of plane strain. When the nature of the contact prohibits any parting at the body–sediment interface, a general relationship covering the different parameters governing the phenomenon can be solved by studying a single unit system. This study was carried out numerically using plasticity finite element programs that were able to take into account precisely the geometry of the body, the characteristics assigned to the sea bed to define the heterogeneity of its cohesion, and its anisotropy, as well as two extreme behaviours at the interface. The results obtained were validated by a series of experimental results from in situ and laboratory tests.

Stochastic theory of settlement of loose cohesionless soils / P. L. Bourdeau in Géotechnique, Vol. 39 N°4 (Decembre 1989)

A model is proposed that is based on the combination of the diffusion of intergranular forces and an excess volume of voids. In this regard, it provides a bridge between theories developed independently for the diffusion of stresses and for the propagation of settlements. In its general formulation, the theory can model three-dimensional, transient effects. However, the model is believed to be limited to normally consolidated, fully drained or dry, soils which do not exhibit dilatancy effects. The modelling of the steady state deflexion pattern under a rigid strip footing was found to be in good agreement with observed settlements in laboratory model tests using uncompacted silt, provided the applied load did not approach the bearing capacity of the soil.

The specimens used in both methods were prepared in the laboratory under controlled conditions to ensure repeatable results. A conventional triaxial cell was used to confine the samples, and full saturation of the specimens was ensured by applying a constant level of back pressure. Accurate flow (inflow and outflow) measurements were obtained using precision burettes and a calibrated flow pump with known flow rates. Fine and coarse materials were tested under different conditions, and effects of different variables including void ratio, hydraulic gradient, specimen size and soil type were studied using the two methods.

Interpretation of creep of soils by rate process theory / J. Feda in Géotechnique, Vol. 39 N°4 (Decembre 1989)

Both types of creep are governed by the same creep laws. In the course of creep, either time- (and strain) dependent structural hardening or softening occur, the first one being typical for volumetric creep, the second one for distortional creep. Some deviations are to be expected with anisotropic soil structure (for example, with presheared samples). Rate process theory, intended for the description of secondary creep rate, may be generalized by taking into account the structural changes of soils (hardening and softening of structure, as characterized by the increase or decrease of the number of structural bonds). In such a case, secondary creep results from the balance of strain-hardening and strain-softening (the first one typical for primary creep, the second one for tertiary creep), which is delicate enough for secondary creep to extend through more than a small time interval.

Data are described from two test-bed sites, one with heavily over-consolidated clay, and one with normally consoli-dated clay. These confirm that a residual shear surface is formed adjacent to the pile shaft during installation. Comparisons with other site investigation data and cavity expansion theoretical predic- tions suggest that stress relief immediately behind the pile tip during installation gives rise to total radial stress and pore pressure measurements on the shaft which are lower than the simple cavity expansion model predicts. However, the data did indicate that the radial effective stress might be successfully predicted. During reconsolidation, the radial effective stress drops initially, followed by a slow recovery, which was insufticient in the two clays investigated for the final value to reach that during installation. On undrained loading, the clay adjacent to the pile did not reach a critical state as many current theories assume, as failure occurred on the residual surface created during installation. The generation of negative excess pore pressures on the shear surface during undrained loading caused an increase in the radial effective stress. In the normally consolidated clay this was solely responsible for the large set-up of pile shaft capac-ity by comparison with that during installation. The same capacity increase may not be seen in these clays if loading were drained.
