Abstract

It is nowadays well appreciated that dams built in narrow canyons exhibit a stiffer response than those in wide canyons, due to the confined geometry of the canyon banks. The numerical modelling of dams in wide canyons is usually considered as computationally less expensive than those in narrow canyons. This is because the former can be idealised by a two-dimensional plane-strain model, while the latter requires a full three-dimensional analysis to appropriately consider the stiffening effect of the narrow canyon geometry. This paper presents a computationally-efficient way to consider the stiffening effect of a narrow canyon in a two-dimensional analysis by using an appropriately increased material stiffness.
