关于“衬砌工程冻害新思维”问题的商榷

中国农业大学低温工程试验研究室刘镜仁同志,在《渠道（沟）衬砌工程冻害治理的新思维及试验研究》一文中,提出了一些与《渠系工程抗冻胀设计规范》ＳＬ２３－９１相左的观点文章有针对性地论述了渠道衬砌中的冻害研究范畴、渠床的冻胀融沉和衬砌体的破坏、允许冻胀位移值与允许残余变形量等问题．并介绍了《渠系工程抗冻胀设计规范》编制中的一些情况

Discussion on the Problem of" A New Thinking on theFrost Damage of Lining Works

A view point different from the" Design Specification of Frost Damage Control for Channel Works, SL23-91" was set forward in a paper titled" Experimental Study on the New Thinking ofFrost Damage Control for Channel/ Ditch LiningWorks" by Liu Jingren, Low-temperature Engineering Department, China Agricutural University.For the sake of discussion on this view point, this paper expounds the research category of frost damage tochannels, frost heaving and thaw settlement of channel bed and damage of lining, allowable displacementof frost heaving and remaining deformation etc. Inthis paper some conditions during compilation of the"Design SPecfication of Forst Damage Control forChannel Works" are presented as well.
