Many concrete face plates of rockfill dams in cold region should be built by one-off construction technique due to limits of duration and weather conditions. The present paper focuses on the impacts of properties of raw materials, environmental conditions, rockfill structure and properties of interaction zone, curing method as well as insulation measures on the cracking performance of concrete face plate. In association with field test data of cracks, the causes of a long concrete face plate in cold region built by one-off construction technique are symmetrically analyzed. Investigations reveal that high adiabatic temperature rising, temperature shrinkage, autogenous shrinkage and drying shrinkage are internal causes of the cracks of concrete face plate in construction stage. Meanwhile, high casting temperature, large temperature difference between day and night, low temperature of maintenance water, and also temperature reduction in winter, as environmental causes, accelerate the crack of concrete face plate. Constraints of interaction zone exert significant impacts on the state, level and distribution of stress. Emulsified asphalt is helpful to reduce the constraints of interaction zone and brings down the cracking risks of concrete face plate.Elements including properties of raw materials,structure of rockfill and interaction zone,and environmental causes should be seriously considered in the design stage,construction stage and curing stage of concrete face plate.
