“…The differences in the temperature distribution in the linear elastic analyses and modified Cam clay analyses were insignificant. This is due to negligible contribution from mechanical terms to the heat equation (7), and also due to the relative insensitivity of the thermal capacity of the soil to changes in voids ratio. Figure 4 illustrates the isochrones of radial displacement in the analysis A2.…”

SUMMARYThe problem of fully coupled consolidation and heat flow around a rigid cylindrical heat source buried in clay has been studied. The governing equations of the problem are summarized in the paper and a finite element time-marching scheme to obtain an approximate solution to the governing equations is described. The stress-strain behaviour of the skeleton of the saturated soil has been represented by both a linear elastic model and the modified Cam clay soil model. The results of a limited parametric study are presented with the aim of understanding the major mechanisms of soil behaviour close to buried canisters of hot radioactive waste. A range of soil properties has been included in the study, and the effects of soil disturbance during canister emplacement have also been considered.

“…Booker and Savvidou and Savvidou and Booker extended Biot's theories including the thermal effects; they proposed analytic solutions for thermal consolidation responses around the spherical and point heat sources of constant strength. Britto and his coworkers used finite element method to analyze the coupled heat flow and consolidation of the seabed with a buried high‐level radioactive waste. Giraud and Rousset developed a solution for one‐dimensional and non‐isothermal consolidation problems of thermal poroelastic media with compressible constituents due to a deep buried spherical decaying heat source.…”

SUMMARYThis paper presents an analytical layer element solution to axisymmetric thermal consolidation of multilayered porous thermoelastic media containing a deep buried heat source. By applying the Laplace-Hankel transform to the state variables involved in the basic governing equations of porous thermoelasticity, the analytical layer elements that describe the relationship between the transformed generalized stresses and displacements of a finite layer and a half-space are derived. The global stiffness matrix equation is obtained by assembling the interrelated layer elements, and the real solutions in the physical domain are achieved by numerical inversion of the Laplace-Hankel transform after obtaining the solutions in the transformed domain. Finally, numerical calculations are performed to demonstrate the accuracy of this method and to investigate the influence of heat source's types, layering, and the porous thermoelastic material parameters on thermal consolidation behavior.

This paper provides a comprehensive survey of the numerical methods related to geotechnical problems, most of which were reported in papers appearing in Soils and Foundations. The reason why most of the reviewed papers are concentrated in Soils and Foundations is that if we were to include papers appearing in other journals in theˆeld of geotechnical engineering, closely related to numerical methods, e.g., Computers and Geotechnics, Int. J. Numer. Anal. Meth. Geomech., etc., we would have to deal with almost all the papers in those journals. Firstly, we present a description of the current status of the numerical methods, and then give a brief review of the literature covering several topics in geotechnical applications. The scope of the review is limited, and thus, the authors do not profess to cover the entire range of literature.
