摘　　要：以实际工程为例,从混凝土内在质量即配合比本身和施工中人为因素两方面分析混凝土冻害原因,并针对混凝土配合比和施工过程如何提高寒冷地区水工混凝土抗冻性进行了论述,为偏远地区水利工程混凝土施工中防冻提供借鉴。Through an example of one hydraulic engineering, the paper analyzes the causes of concrete frost on the base of concrete quality—the mix proportion and person factors. Pointing to the concrete mix proportion and the course of engineering building ,the paper also discusses the measures to improve the frost resisting property of hydraulic concrete in cold zone,in order to give the measures how to protect the hydraulic engineering against freezing.

关 键 词：混凝土 配合比 抗冻性
