摘　　要：水资源短缺已是中国目前面临的突出问题之一,在这个背景下,如何把“节水优先”落到实处,消除制约经济社会发展的瓶颈,是当前工作的重中之重。渠道混凝土衬砌是落实节约用水的重要举措,渠道混凝土衬砌质量的好坏,关系到工程正常输水供水、安全运行和经济效益的发挥,对促进农业生产、生活用水、生态供水具有重要影响,文章结合国家当前大规模实施水利工程建设的实际,对渠道混凝土衬砌面板冻胀进行简要分析,简述渠道混凝土衬砌面板冻胀裂缝主要成因,详细阐述渠道混凝土衬砌面板冻胀裂缝预防措施和处理对策。以期对渠道混凝土施工冻胀混凝土裂缝进行防治,更好地发挥工程效益。Water shortage has become one of the most prominent problems facing China at present. In this context, how to put“water saving priority”into practice and eliminate the bottleneck restricting economic and social development is the top priority of current work.Channel concrete lining is an important measure to carry out saving water The quality of canal concrete lining is related to the normal water supply, safe operation and economic benefits of the project, and has an important impact on promoting agricultural production, domestic water and ecological water supply. Combining with the current state of large-scale implementation of the construction of water conservancy projects in China, this paper briefly analyzes the frost heave of channel concrete lining panel, describes the main causes of frost heave crack of channel concrete lining panel, and expounds the prevention measures and treatment countermeasures of frost heave crack of channel concrete lining panel in detail, in order to prevent and control the crack of frost heave concrete in channel concrete construction, better exert the engineering benefit and ensure the smooth implementation of agricultural irrigation.
