Abstract

Three scaled-down ( 1 :40) models of a gravity dam are subjected to an equivalent hydraulic and dead weight loading. An initial notch the upstream side propagates during the loading towards the foundation. After the peak value, the testing machine switches from to load control and executes three steps: unloading, reloading load until failure. A numerical simulation of the experiments is using a time-dependent cohesive crack model in Mixed-mode The structural behaviour of the models, in terms displacements and failure lifetime are reproduced by idealisation in a satisfactory manner.
