Abstract:
Crosshole seismic tomography characterization of Baixo Sabor dam’s rock mass foundation after the first filling of the reservoir is presented. A continuous foundation profile along the dam’s reference line was obtained with P-wave seismic velocity distribution. This zoning was used to adjust the foundation mechanical parameters of dam´s finite element model. The model, developed by LNEC, included a 3D representation of the dam and its rock mass foundation, was used for the analysis and interpretation of dam´s structural behaviour during the first filling of the reservoir and the subsequent operation period.
