description: In this work, a refinement of the finite element model of a gravitational concrete dam was carried out in a software package. Experimental frequencies and forms of natural vibrations of the dam-base system obtained as a result of vibration tests were used to calibrate the model. The peculiarity of this dissertation is that the calibration was performed on the basis of a significant number of parameters, which included the elastic modulus of the dam and rock foundation materials. Two different time periods were considered, which is the first step towards taking into account external factors such as, for example, the water level in the reservoir. The results presented in this paper can be used as prerequisites for the creation of tools to help diagnose the current state of the dam.
