The paper describes the results of making the mathematical and physical models of the authors, by using analogous methods and materials. There is the mathematical rock mass deformability model as a base for foundation engineering a concrete arch dam and the physical rock slope model which was tested by loading until failure and the results were compared with the calculation procedure. In the first example the correlation is established between the static and the analogous dynamic in situ investigations for creating the mathematical rock mass deformability model. In the second example there is application of the analogous materials for the discontinuity shearing simulation on the physical slope model. The results of the geotechnical in situ investigations and laboratory testing carried out in the Institute for Development of Water Resources "Jaroslav Cerni" in Belgrade were used for making the models. U radu su dati rezultati izrade matematickih i fizickih modela autora, dobijenih koriscenjem analognih metoda i materijala. Prikazan je matematicki model deformabilnosti stenske mase kao podloge za fundiranje lucne betonske brane i fizicki model stenske kosine na kome su izvrseni ogledi opterecivanja do loma i rezultati uporedjeni sa racunskim postupkom. U prvom primeru uspostavljena je korelaciona veza izmedju statickih i analognih dinamickih ispitivanja in situ za dobijanje matematickog modela deformabilnosti stenske mase. U drugom primeru pokazana je primena analognih materijala za simulaciju smicanja po pukotinama na fizickom modelu kosine. Za izradu modela korisceni su rezultati geotehnickih ispitivanja in situ i laboratorijskih ispitivanja izvrsenih u Institutu za vodoprivredu "Jaroslav Cerni u Beogradu.
