Tensiones y deformaciones de la presa de Zahara

The paper describes the data observed during the construction of Zahara dam (southern Spain) and its interpre­tation by means of a finite element model of the main cross section. Zahara dam has a central core of weathered marls and outer shells of granular alluvium and quarried limestone. Its foundation consists of almost vertical alternating strata of tertiary marls and sandstones. The mathematical formulation of the finite element model used for the interpretation includes the effect of time for the si­mulation of construction as well as for the period of observation after the end of construction. It also includes the effect of wetting deformations to predict movements and stresses during the filling of the reservoir which is starting these days
