    Alternative formulations for cyclic nonlinear models: parametric study and comparative analyses

    , 7th European Conference on Numerical Methods in Geotechnical Engineering, Pages: 423-428

    The utilisation of cyclic nonlinear elastic models presents numerous advantages when analysingsimple dynamic problems, such as one-dimensional site response. This class of models requires a small numberof parameters to be determined and can efficiently reproduce the strain dependency of the secant shear stiffnessand hysteretic damping. However, it has been frequently noted that, for medium to large deformation levels, thepredicted damping ratio can be significantly larger than the values evaluated for most soils through laboratorytesting. To minimise the effects of this overestimation on the overall response of the system, which may lead tonon conservative results, different formulations have been proposed. In this paper, two alternative expressionsfor the stress-strain behaviour of soils – hyperbolic and logarithmic – are presented and their ability to reproducewell-established empirical stiffness degradation and damping ratio curves is assessed. Finally, the results of a setof dynamic finite element analyses of a one-dimensional wave propagation problem are presented to illustratethe impact of the different formulations on the engineering behaviour of soil deposits.

    Structural evolution of minibasins on the Utsira High, northern North Sea; implications for Jurassic sediment dispersal and reservoir distribution

    , Petroleum Geoscience, Vol: 16, Pages: 105-120

    3D seismic and well data are integrated to determine the tectonostratigraphicevolution of the SW margin of the Utsira High, northern North Sea riftsystem. During the Triassic, a series of minibasins formed due to passive diapirismof the evaporite-bearing, Upper Permian, Zechstein Supergroup. Subsequently,during the Jurassic, a series of secondary minibasins developed as the underlying saltwalls collapsed. These minibasins were a few hundred metres deep, bound bysub-circular to elongate salt-cored structural highs and caused the development ofcomplex subaerial topography and submarine bathymetry on the SW margin of theUtsira High. Salt withdrawal may have been related to: (i) partial dissolution of salt;(ii) differential erosion of the salt walls and adjacent Triassic-filled minibasins; or (iii)salt remigration caused by sub- or supra-salt extension or sediment loading. Thisstudy provides insights into the tectono-stratigraphic evolution of the SW margin ofthe Utsira High and has implications for (i) facies distribution of the ZechsteinSupergroup within the northern North Sea rift system; and (ii) depositional systemdevelopment, and thus reservoir distribution, within the Jurassic sedimentarysuccession.

    A constitutive model for the behaviour of shotcrete

    , Pages: 49-60

    A constitutive model for the behaviour of shotcrete is presented in this paper. It is formulated within the framework of elasto-plasticity and the smeared crack concept is applied. Two independent yield surfaces govern the mechanical behaviour under compression and tension, which is further controlled by non-linear hardening and softening. The main material parameters are assumed to change with time. Validation of the model has been achieved by fitting the increase in stiffness and strength to published data in the literature. Good agreement is found between predictions of the complete stress-strain curves of shotcrete at different ages and experimental results. The model represents a sophisticated tool for the realistic analysis of tunnels, which are driven according to the principles of the New Austrian Tunnelling Method (NATM).
