ABSTRACT: Due to proper technical characteristics, economic and operating considerations, the clay core earth dams have such a special place in the world. In this kind of dams, the implementation of their core and adjacent filters are placed in the critical path of dam construction, while the coarse grain shells are performable easily and quickly. Considering this fact, the possibility of replacing the clay core with other appropriate sealing materials, has been studied. The discussed idea in this field is the implementation of plastic concrete in the center of the dam body with the stage drilling in coarse grain shells. The most concern are related to the rigidity of the plastic concrete wall in comparison with the dam’s gravelly shells and also the pressure and tension/stress transfer to the wall in the dynamic and static conditions. In this paper, with a numerical method, the performance of the proposed cut-off wall in the body of a reservoir dam (Soombar reservoir dam).The static analyses show there is a possibility of developing cracks in cut-off wall, and due to technical issues this replacement is not possible for Soombar dam.
