Abstract: As a common aging problem caused by the extreme climate in cold region, frost damages lead the structural performance to deterioration with a high probability, especially on the damming concrete widely used in the hydropower project, evenly resulted in unpredictable damages and an adverse effect to the service life of the project. On the basis of statistics, the problems existed and research situation, emphases on the theory research, test method, numerical simulation, damage identification, suppression and monitoring inhibit repair, etc., are discussed for the research of freeze-thaw diseases on hydraulic concrete. Suggested with the study, the research of the deterioration mechanism and improved test method subjected to freeze-thaw cycles should be strengthened with the coupled action of multiple damage factors, effective 3D multi-scale model, calculation methods and tools need to be developed to realize the fine numerical simulation of the freeze-thaw diseases process of hydraulic concrete in complex environment, in order to form a complete hydraulic concrete from research ideas, methods to engineering practice freeze-thaw preventive control theory.

Key words: hydraulic concrete, frost damage, numerical analysis, impact assessment, preventive control
