    I am scared about the reviews but I want to know what is the concept behind this idea. 
    Why can't we use a base isolation system for Dam structures? If it can reduce the frequency of the structure very significantly, why is there no research and discussion about this topic?

    Thanks.

    Location constraints. Hydraulic structures/dams are usually located inside water-body. Challenges of conveniently excavating for isolating bases of specific dimensions and depth, could make it difficult for such foundation type to be provided.

    Thank so much for your comprehensive response. In my opinion the listed problems can be addressed by the pre-analysis of the structure,foundation and the isolation system.Though it seems very impractical but the brainstorming is needed for this topic. I've done some preliminary analysis and the results were quite pursuing but as a reference solution, idea, and research I found the topic very lonely..

    Decoupling a dam from its foundation would compromise its ability to retain the reservoir. You raise an interesting question and I encourage you to keep thinking out of the box.
