Abstract :
    Destruction factors of underground dams can be divided into three main categories of hydraulic demolition, water leakage and construction demolition. The purpose of this research is to identify the causes of underground dam destruction through library studies. In addition to the walls of the dam, the main variables affecting the behavior of groundwater in the bedding of the dam and reservoir as well as geological materials are important factors in the sustainability of underground dams. In this research, the reasons for the destruction of underground dams are based on site conditions. The results of the studies showed that hydraulic degradation and degradation due to contamination from salt formations are in the first priority.
