Earthquake effects, hydrodynamic forces, and nonlinear effects (structure properties represented by elastic constants) on rock-fill dam vibrations are investigated with a special case in the Jatiluhur dam, Indonesia. The vibration was studied by using the Single Degree of Freedom (SdoF) model with hydrodynamic forces and earthquakes as external forces. The analytical solution is obtained by the Laplace transform. Variations in hydrodynamic forces are obtained from water level measurement data where three scenarios are carried out, namely the lowest water level, middle and highest. The results show that the resulting hydrodynamic force does not have a significant effect on the vibration of the dam. The change in the vibration amplitude corresponds to the earthquake amplitude when the earthquake ends. The effects of the earthquake are still felt for a few seconds. The second model is to study the inhomogeneous-isotropic behavior of the Dam constituent material in a nonlinear elastic coefficient. We express the elastic properties of the material in terms of the Taylor expansion. By using the Taylor expansion for the nonlinear effect up to the fifth-order show that the nonlinear term did not give effect on the vibration amplitude but the vibration shift.
