Kovacevic N, Potts DM, Vaughan PR, 2008, Recent advances in the numerical modelling of embankment dams, Pages: 164-176

The main concern when designing or analysing embankment dams is usually their stability. However, assessing their deformation is also important. This paper describes the recent use of advanced numerical analysis to predict the latter. Examples of its use in assessing likely movements of six embankment dams constructed in the UK are provided. Various phases in dam life are considered: embankment construction, first reservoir impounding, subsequent reservoir operation and raising the crest level. The use of adequate constitutive laws and, in particular, the importance of modelling the plastic behaviour of embankment fills during loading, unloading and re-loading is clearly demonstrated.

Kontoe S, Zdravkovic L, Potts DM, Menkiti COet al., 2008, Case study on seismic tunnel response, Canadian Geotechnical Journal, Vol: 45, Pages: 1743-1764

This paper presents a case study of the Bolu highway twin tunnels that experienced a wide range of damage during the 1999 Duzce earthquake in Turkey. Attention is focused on a particular section of the left tunnel that was still under construction when the earthquake struck and that experienced extensive damage during the seismic event. Static and dynamic plane strain finite element (FE) analyses were undertaken to investigate the seismic tunnel response at two sections and to compare the results with the post-earthquake field observations. The predicted maximum total hoop stress during the earthquake exceeds the strength of shotcrete in the examined section. The occurrence of lining failure and the predicted failure mechanism compare very favourably with field observations. The results of the dynamic FE analyses are also compared with those obtain by simplified methodologies (i.e. two analytical elastic solutions and quasi-static elasto-plastic FE analyses). For this example, the quasi-static racking analysis gave thrust and bending moment distributions around the lining that differed significantly from those obtained from full dynamic analyses. However, the resulting hoop stress distributions were in reasonable agreement.

The performance of the generalized-α, Newmark, HHT and WBZ time integration schemes is examined for a boundary value problem of a deep foundation subjected to various earthquake loadings. The effects of the frequency content of the earthquake excitation and the natural frequency of the numerical model on the performance of the above-mentioned algorithms are considered. The various time integration methods are compared in terms of accuracy, the ability to control high-frequency dissipation and run time. It is concluded from the finite element analysis results that the generalized-α scheme has superior qualities compared to the other algorithms investigated.

Schroeder FC, Day RA, Potts DM, Addenbrooke TIet al., 2007, Quadrilateral isoparametric shear deformable shell element for use in soil-structure interaction problems, International Journal of Geomechanics, Vol: 7, Pages: 44-52, ISSN: 1532-3641

In the finite-element analysis of soil-structure interaction problems, shell elements are important to model structural components such as tunnel linings or sheet pile walls. In this paper the development, implementation, and testing of a curved quadrilateral isoparametric shear deformable shell element are presented. An overriding concern in the analysis of soil-structure interaction problems is the C0 compatibility of the shell elements with the solid elements used to model the soil. Many recent publications on shell elements deal with the elements in a purely structural context and therefore do not require the C0 compatibility with solid elements. The development of the shell element presented here forms an extension of a new approach to curved Mindlin and axisymmetric shell elements introduced by Day and Potts in 1990. There are no generally accepted benchmarking marking problems for the use of shell elements in three-dimensional geotechnical engineering problems. Consequently, the performance of the shell element is first assessed by analyzing standard structural benchmarking problems. It is found that the new element performs well compared to other elements used in a purely structural context. Further, it is demonstrated that the same element that is used to analyze curved shells can be used to analyze flat plates without the requirement of a different formulation. Finally, the performance of the new shell element is compared with a closed form solution in the analysis of a deep tunnel. © ASCE.
