Abstract

A Comparison between Actual Displacements and Numerical Results from a Finite Element Model in an Arch Dam L.E. Romera, S. Hernandez E.T.S. Ingenieros de Caminos, Canales y Puertos University of La Coruna, La Coruna 15071, Spain ABSTRACT A comparative study between recorder displacement data of the Belesar arch dam in Spain and displacement fields provided by a structural analysis carried out of a finite element mesh is presented in this paper. In addition to the usual loads as weight material, water pressure and temperature changes, an expansive process of geochemical origin has been considered in the analysis. Numerical results showed good accuracy, with better performance in downstream displacement. 1. INTRODUCTION The Belesar Dam is an arch dam located in North West Spain. It has a height of 130 m and its maximum length at the top dam is about 600 m. Figure 1. Picture of Belesar Dam
