本文根据工程成败实际情况总结提出“渠坡基土的稳定是混凝土衬砌不被冻融破坏的关键”的观点!作了四方面的阐述:1、题目本身就强调,在制定工程抗冻措施时,重点应放在渠基的处理上;2、一些成功的工程抗冻经验和措措,都反统一到它保证了渠基稳定上来认识;3、以提高土壤密实度为目的进行换基又是渠基处理的重点,只要密实,换填材料不拘一种;4、没有换填条件,就应采取相应的渠道结构型式来抵抗渠基失稳。
Based on the actual situation of the project, this paper summarizes the viewpoint that “the stability of drainage slope foundation soil is the key point of concrete lining not being damaged by freezing and thawing”! The paper elaborates on four aspects: 1. The subject itself emphasizes that when formulating engineering freezing resistance measures , The focus should be placed on the treatment of canal foundation; 2, some successful engineering experience and measures against freezing, anti-unification to ensure that it is to ensure the stability of the foundation; 3, in order to improve soil compaction Is the focus of the drainage foundation treatment, as long as the dense, fill the material for one; 4, without replacement conditions, it should take the appropriate channel structure to resist the instability of the foundation.
