    Simulation of excavation in a poro-elastic material (1992)

    Notes: A method is presented which allows the computation of the displacements and pore pressures which are generated in an elastic soil when excavation is carried out. The formulation is based on Biot's theory and is fully coupled, with consideration also given to the effects of the lowering of the water table which often accompanies the excavation of soil. Example problems are solved to illustrate the theory which has been presented.

    Finite layer analysis of the behaviour of a raft on a consolidating soil (1994)

    Notes: A numerical method is developed in this paper for the analysis of the behaviour of a raft resting on a consolidating soil. The response of the raft under an applied loading is determined using the finite layer method for the soil and the finite element method for the raft. By considering deflection compatibility on the contact surface, the distribution of contact pressure is computed at various time steps. The settlement and bending moment in the raft is then evaluated by applying the calculated contact pressure back to the raft. It is shown that, in some cases, the maximum moment in the raft occurs during consolidation and that checking the final moment in the raft by use of elastic theory may not be sufficient.

    Consolidation of clays subjected to three-dimensional embankment loadings (1991)
    New York, NY [u.a.] : Wiley-Blackwell
    International Journal for Numerical and Analytical Methods in Geomechanics 15 (1991), S. 857-870

    Notes: A Fourier transform technique is presented which may be used to analyse three-dimensional consolidation problems for soils which are loaded by embankment shaped loadings that are rectangular in plan (or of arbitrary shape which can be divided into rectangles in plan). The introduction of a Fourier transform effectively reduces the three-dimensional problem to one involving only two spatial dimensions and this reduces computer storage and saves computing and data preparation time. The material properties of the soil may vary arbitrarily in the plane which is perpendicular to the axis associated with the variable eliminated during the Fourier transform. Solutions obtained using the method are compared with existing solutions in order to verify the theory and assess accuracy, and illustrative examples are given for problems involving the consolidation of soils under embankment loadings.

    Finite layer analysis of laterally loaded piles in cross-anisotropic soils (1991)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: This paper presents a finite layer method for the analysis of laterally loaded piles in isotropic and cross-anisotropic layered soils. Excellent agreement is found between the isotropic solutions computed by the finite layer method and the more rigorous finite element method. Some theoretical solutions are presented to demonstrate the effect of soil anisotropy. Two full scale field case histories have been analysed by the method using isotropic and cross-anisotropic soil models.
