Abstract :
    The most important factors in the design of the body of the underground dam with high depth are impermeability, flexibility, plasticity, strength, stability and cost-to-productivity ratio of the dam. Plastic concrete has low permeability and high plasticity. plastics concrete, which is a type of concrete , includes sand, cement, water and Bentonite with high ratio of water-cement to produce a soft and flexibility material. a impermeable wall of plastic concrete is used as a barrier to stop or reduce the flow of underground water. In this paper, the principles and rules for the design and implementation of underground dams using plastic concrete have been investigated.
