摘要
深入分析了季节性冻土区渠道冻害的原因,概括了目前抗冻胀防渗渠道的主要结构形式,结合国外较成熟的GCL渠道防渗结构技术,对我国经济合理且抗冻胀的新型渠道防渗结构形式进行了探讨,对进一步研究季节性冻土区渠道防渗具有借鉴意义。
This paper deeply analyzed the reason for frost damage of channel in seasonal frozen soil regions, summarized the main structure forms of seepage prevention with frost heaving resistace at present. Combined with the successful technology of GCL in abroad, the new canal structure forms of seepage prevention are discussed which can resist frost heaving and are economical and resonable. There are some reference for further research of seepage prevention of channels in seasonal frozen soil region.
