本文主要讨论了渠道衬砌允许冻胀变位值问题。根据当前渠道抗冻设计提出的允许冻胀变位值,文中提出几点不同看法,说明在进行衬砌抗冻设计时,要立足于对衬砌不允许有任何冻胀变形的设计思想,以确保抗冻设计安全可靠。对工程设计施工具有一定指导意义。
This article mainly discusses the problem of allowable displacement of canal lining. According to the allowable frost heave displacement value proposed by the current antifreeze design, several opinions are put forward in the paper, which shows that in the design of antifreeze lining, we should base ourselves on the design idea that the frost heave deformation should not be allowed to the lining to ensure the anti- Frozen design safe and reliable. The project design and construction has some guiding significance.
