Anti-frost Expansion Damage and Control Measures for Tenth Agricultural Division 183 Regiment Dongchang Branch Ditch

渠道防渗衬砌冻胀破坏的主要影响因素有渠床土质、冻土深度、地下水埋深、衬砌结构形式及材料等。本文根据当地实际情况,结合冻胀计算结果,指出选择合理衬砌材料、衬砌结构、衬砌断面形式,同时应用防渗材料、换填非冻胀性土、隔热保温等削减或适应冻胀的措施,可以有效防治渠道冻胀破坏。

Main influence factors of channel impermeable lining frost expansion damage include channel bed soil quality, permafrost depth, groundwater depth, lining structure and materials, etc. The paper combines frost expansion calculation results on the basis of local conditions to indicate that choosing proper lining materials, lining structure, lining section form and the application of impermeable material, replaced filling of non-frost expansion soil, thermal insulation and other measures to reduce or adapt frost expansion can effectively prevent frost expansion damage.
