Elastic analysis of an arch-gravity dam using DIANA

Gerd-Jan Schreppers, Giovanna Lilliu (TNO DIANA BV)

Modelling and analysis with DIANA Finite Element Software of the La
Aceña arch-gravity dam are presented in this paper. Comparison between calculated and
measured displacements shows reasonable agreement. Thermal expansion of the dam as
well as foundation properties appears to have major impact on the calculated results. The
different analyses reported in this study provide insight in the effect of e.g. water
temperature, environment temperature and foundation stiffness on the deformations of the dam.
