在渠道衬砌损坏情况调查分析的基础上，总结了衬砌渠道损坏的主要形式，并对每种损坏形式进行了原因分析，指出边坡陡、基土冻胀变形、基土渗透变形及渗透压力的作用是造成衬砌损坏的主要原因。针对损坏原因，从设计、施工和管理上找出了对策。此外，据韩墩总干衬砌渠道的损坏情况，肯定了在季节性冻土地区通过渠道衬砌实现基土保温的必要性。 Based on the investigation and analysis of the damaged condition of the lining, the main forms of the damaged lining of the lining are summarized, and the causes of each damage form are analyzed. It is pointed out that the steep slope, the frost heave deformation of the soil, the infiltration deformation of base soil and the infiltration pressure The role of lining is the main reason for damage. For the reason of damage, from the design, construction and management to find out the countermeasures. In addition, according to the damage condition of the main channel of HanDun pier, the necessity of insulation of the soil through the channel lining in the seasonal frozen soil area is affirmed.
