Influence of past loading history on the seismic response of earth dams

A Study to Evaluate the Seismic Response of Road Embankments

“…The model is illustrated in APPENDIX 1 and has proved to be suitable in catching the behaviour of diŠer-ent geotechnical structures subject to earthquakes (e.g., Sica et al, 2008). Its main features are: -the possibility to account for rotation of principal stresses, through the deˆnition of three plane mechanisms, deˆned in the generic stress plane p k -q k , where:…”

Numerical investigation of the response of the Yele rockfill dam during the 2008 Wenchuan earthquake

“…In these applications, the constitutive models can be usually categorised into: linear and equivalent-linear models (Clough and Chopra, 1966;Seed et al, 1969;Vrymoed, 1981), cyclic nonlinear formulations coupled with simple elasto-plastic models (Prevost et al, 1985;Pelecanos, 2013;Pelecanos et al, 2015), advanced elasto-plastic models (e.g. multi-surface kinematic hardening models) usually simulating clay core dams (Sica et al, 2008;Elia et al, 2011) and advanced elasto-plastic models (e.g.…”

A case study on the seismic performance of earth dams

“…Subsequent finite element (FE) studies concentrated on the three-dimensional (3D) analysis of earth dams (Griffiths & Prevost, 1988;Dakoulas, 2012), elasto-plastic behaviour of the soil materials (Prevost et al, 1985;Woodward & Griffiths, 1996), hydrodynamic pressures on dams , coupled-consolidation analysis (Lacy & Prevost, 1987;Sica et al, 2008, Elia et al, 2010 and estimation of critical seismic coefficients ) using constitutive models of various levels of complexity. The FE method is considered one of the most powerful tools to analyse the response of dams during earthquakes, however most of the numerical studies mentioned…”
