Groundwater pollution by organic compounds: a three-dimensional boundary element solution of contaminant transport equations in stratified porous media with multiple non-equilibrium partitioning
Autor: J. R. Booker, Abbas El-Zein
Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 23:1733-1762
Industrial contaminants and landfill leachates, particularly those with high organic content, may migrate into groundwater streams under conditions of non-equilibrium partitioning. These conditions may either be induced by time-dependent sorption ont

Groundwater pollution by organic compounds: a two-dimensional analysis of contaminant transport in stratified porous media with multiple sources of non-equilibrium partitioning
Autor: J. R. Booker, Abbas El-Zein
Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 23:1717-1732
Transport of pollutants in soil and groundwater often occurs in stratified media under non-equilibrium conditions. Confined aquifers are usually bounded by low-permeability layers of soil which have been shown to exert a significant influence on the

Green's functions for a fully coupled thermoporoelastic material
Autor: J. R. Booker, David Smith
Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 17:139-163
The Green's functions for a set of fully coupled linear equations governing thermal consolidation of a homogeneous isotropic material are presented. The Green's functions are evaluated for one, two and three spatial dimensions, and in the Laplace and

Integration of Tresca and Mohr-Coulomb constitutive relations in plane strain elastoplasticity
Autor: Scott W. Sloan, J. R. Booker
Publikováno v: International Journal for Numerical Methods in Engineering. 33:163-196
SUMMARY This paper considers the problem of integrating the constitutive relations for Tresca and Mohr-Coulomb materials under conditions of plane strain. In the case of a Tresca material, we show that the constitutive law may be integrated exactly b

Application of discrete Fourier series to the finite element stress analysis of axi-symmetric solids
Autor: J. Y. Lai, J. R. Booker
Publikováno v: International Journal for Numerical Methods in Engineering. 31:619-647
This paper describes an efficient formulation, based on a discrete Fourier series expansion, for the analysis of axi-symmetric solids subjected to non-symmetric loading. In contrast to the commonly adopted continuous Fourier series approach, the disc

The effect of increasing strength with depth on the bearing capacity of clays
Autor: J. R. Booker, E. H. Davis
Publikováno v: Géotechnique. 23:551-563
By means of the theory of plasticity, solutions are obtained to the problem of bearing capacity of clay (φ=0) which is inhomogeneous in the vertical direction only. It is shown that the rate of increase of cohesion with depth plays the same role as

The behaviour of footings resting on a non-homogeneous soil mass with a crust. Part II. Circular footings
Autor: R K Rowe, J R Booker
Publikováno v: Canadian Geotechnical Journal. 18:265-279
A convenient and economical finite layer method of analysing the behaviour of footings on a non-homogeneous soil is outlined. This method of analysis is used to investigate the elastic response of strip footings for a wide range of soil profiles invo
