Abstract
In this paper a comprehensive study of the existing Spanish dam of Bolarque is presented. The dam was composed of two different classes of concrete and also two choices of material characteristic of the rock foundation were considered. The seismic analysis was earned out taking in account the dam-foundation rockimpounded water interaction. Additionally, thermal loadings were included by using an equivalent structural model. Overall 128 structural analyses were carried out to complete consider the necessary combinations of materials, seismic and thermal loadings. Numerical results are presented showing the behaviour of the dam under the worst situations for empty and full reservoir. 1 . A BRIEF HISTORY OF BOLARQUE DAM The Bolarque dam was built in 1910 and works to increase its height and therefore to improve the volume of impounded water were carried out in 19541955. Figure la shows the cross-section of the dam and Figure Ib the structural model which acommodate quite properly the actual geomeuy.
