Abstract: 
Freezing and thawing damage is one of the major problems of concrete dam in cold climates. Cracking and splitting are the most common results of freezing and thawing deterioration in concrete dam. The cracking problem owing to freezing and thawing was investigated by making use of finite element methods. The interpretation of the mechanism of failure was also given. The researches show that the first principal stress of concrete dam at downstream surface can exceed the tensile strength of concrete. Prior to repair, a detailed survey was conducted to obtain an overall understanding of the damaged concrete. As for the repair method, the coating method and reinforcing method were taken as the main measures in the rehabilitation of Fengman concrete dams.
