Resumen:
The paper presents a case study of an existing large gravity dam suffering from observed "pathological behavior" due to the swelling of concrete. The analysis allows the numerica1 simulation of several phenomena which are important to model the observed behavior; degradation of concrete under tension and compression creep, internal actions such as swelling, pore-water pressure and seasonal thermal variations, and construction joints. Numerical results are presented and compared with. in situ measurements in order to assess the reliability of the analysis.
