ABSTRACT

The previous investigations for the stability of earth dams with the pseudostatic method are

unsatisfactory,because the results can either becorrect or false. For dam projects in earthquake

regions is of intrest the determination of actual stress-strain behavior of high dams under

seismicloads, instead of a fictitious factor of stability with a static analysis. Therefore a dynamic

numerical ,analyssis under the unfluence of water pore perssure is described, so that the seismic

risk at a proposed dam be evaluated. With the prposed dynamic numerical analysis the stress and

displacements behavior and the water pore persure developed under seismic loads could be

obtained
