摘　　要：新疆气候寒冷,许多混凝土水工建筑物因冻胀破坏而影响正常运用,深入研究冻害产生的客观规律,采用经济合理的抗冻措施,成为水利建设的一项迫切任务。通过对混凝土防渗渠道冻害机理和破坏型式的分析,论述了基土冻胀对混凝土渠道的危害与特点,以及根据具体情况如何选择抗冻措施,为严寒地区混凝土衬砌渠道防冻胀提供参考。Due to the cold weather in Xinjiang, many concrete structures suffer from frost heave that has resulted in damages and affected the normal operation of canal system. It is necessary to carry out in-depth studies on the objective laws of forest heave happening and find out solutions for dealing with the disaster in an efficient and effective way. Examinations are made on harm of foundation soil frost heave to concrete canal and its features based on analysis on mechanism of freezing damage and its type. Anti-freezing measures are proposed by taking the local conditions into consideration. It can provide valuable experiences to the similar areas.
