摘　　要：针对新疆下坂地水利枢纽工程,通过试验设计适应于当地严寒气候的混凝土配合比,为更多类似严寒地区的水利水电工程提供参考和改进依据。试验结果表明:当粉煤灰掺量≤30%时,粉煤灰混凝土的抗冻融性能有所提高,并且随着粉煤灰掺量的增加,粉煤灰混凝土试块的强度和引气剂掺量均减小。With the development of water conservancy and water electricity,the durability of hydraulic structures has attracted more attention,especially in cold regions.This paper discusses the key water projects at the Xiabandi in Xinjiang,designs the concrete mix ratio for the native place by a large number of experiments.The results of tins experiment show that when the fly ash content ≤30%,the freeze-thaw resistance has been improved,and with the fly ash content increased,the strength of concrete and the amount of air entraining agent has decreaseded.
