农一师沙井子灌区混凝土衬砌渠道防冻胀设计的探讨

Discussion on the Design of Preventing Frost Heave of Concrete Lining Canals in Sha-jing- zi Irrigation District of the First Bureau of Agriculture

农一师沙井子灌区属寒冷地区,针对寒冷地区混凝土衬砌体的冻胀破坏问题,根据近年来我国在水工建筑物抗冻技术方面的研究成果,结合本区的实践经验,笔者介绍了沙井子灌区混凝土衬砌渠道的抗冻胀设计方法和切实可行的抗冻胀措施。

Sha-jing-zi irrigation district of the First bureau of Agriculture belongs to cold region, and there usually appears frost heave of concrete lining canals. Based on the research results on the damage of hydraulic structure preventing freezing and combining the experience of the area, the paper introduces the design method of preventing freezing and bloating and its effective measures.
