Effect of the Width of Dam Crest on Seismic Characteristic of Critical Slice Surface on Embankment Dams

Researchers have been investigated methods to precise earthquake effect on behavior of embankment dams in 60 years ago. Researchers have been evaluated different effective parameters. Width of dam crestis main part of the embankment dam. So Evaluation of seismic behavior in different crest width of dam is important. But a few researches have been assessed affect of the crest width in response of seismic parameters. So Masjed Soleiman dam for a case study has been selected. Finite Element model of Masjed Soleiman dam has been constructed in GeoStudio Geoslope v2007 software. Also in constructing of finite element model, has been used of Mohr Coulomb failure criterion for body of dam. For analyses of finite element model, first a layer analysis has been carried out considering 12 layers in end of construction stage. Then, this analysis has been continued considering water table and weight of dam reservoir.
