摘要
在多年工程实践及调查研究的基础上,总结影响渠道防渗衬砌冻胀破坏的主要因素:渠床土质、冻土深度、地下水埋深、渠道走向、衬砌结构形式及材料对衬砌渠道防冻胀的影响,提出选择合理断面形式及衬砌结构、应用防渗新材料、换填弱冻胀性土、隔热保温等削减或适应冻胀的措施。
Based on many years engineering practice and research,the paper summarized the main factors affecting heave-proof for the canal lining such as： the soil texture,the depth of frozen soil,the groundwater table,the canal trend,the lining structure and the material.The article also proposed the reasonable cross section and lining structure,compound lining of membrane material,filling weak heave soil,insulating and preserving heat and so on.
