SEISMIC DEFORMATION ANALYSIS OF EARTH DAMS

This paper describes a procedure for the Seismic Deformation Analysis of earth dams. Based on actual earthquake records, an analytical model was developed for calculation of permanent deformation of earth dams. The method involves the integration of the seismological and geotechnical inputs in a consistent manner to yield the seismically induced permanent deformation of the dam. Then, the proposed deformation model is compared with the deformation of the triangular, sinusoidal, and rectangular pulses, as well as the data by Makdisi and Seed (۱۹۷۸).
