摘要：With regard to importance of stability and safety of dams against incoming loads,it is very important to choose suitable constructions as dam foundation.Bushehr Baghan rolled concrete dam has two different Bakhtiari constructions under its foundation.Existence of many differences in two constructions towards each other,increasingly pay attention to dam dynamic analysis importance and to results comparison between 2D and 3D analysis.Results analysis indicate that there is meaningful difference of maximum horizontal displacement on the top of dam under final loading in two constructions.2D and 3D behavior comparison shows that in similar loading,because of tension distribution and adjustment,replacement and foundation sinking and tensions in 3D state is lower and smaller than 2D state.
