Abstract: This paper reports a case study of the chemo-thermal-mechanical analysis of a concrete arch dam during its construction and first reservoir filling phases. The hydration kinetics model is formulated in the framework of thermodynamics of chemically reactive porous media based in the model presented by Ulm and Coussy. The structural response of the dam is assessed by a viscoelastic model. The parameters of the normalized affinity and the double power creep law are defined based on laboratory tests performed on samples extracted during construction. The predicted temperatures and stresses are compared with the monitoring system values.
