    one of the most important factors in the cracking and destruction of concrete dams is earthquake force. typically, after the earthquake, cracks in the body of concrete dams are observed, and despite the consideration of the necessary arrangements in the design of the dam, due to the formation of tensile forces caused by the earthquake cracking occurs in concrete. if these cracks are not properly restrained, the dam will be damaged. in the present study, we investigate how cracks are created and the factors affecting its formation, how to distribute cracks, the classification of cracks formed in the concrete dams body, and the strategies for preventing or repairing cracks in concrete dams. considering the great sensitivity and importance of the issue of cracking in concrete dams and the inappropriateness of conventional methods, there is a need for extensive studies and studies in this field. the crack range in concrete dams varies from a surface cracking to a concrete breakdown. in fact, the cracks cause openings that can cause further damage to concrete. the occurrence of cracks in concrete dams may endanger the structure of the dam. the occurrence of cracks in concrete sections and bodies of dams indicates a tension or movement that concrete cannot withstand. therefore, concrete dams and their lateral structures should be designed to withstand the hydrostatic pressure of the reservoir water.
