摘要
寒冷地区大中型灌区渠道衬砌冻胀破坏问题非常普遍,尤其是地下水位较高地区,对渠道自身和灌区运行危害很大。通过对渠道冻胀机理分析,根据多年工程经验,从渠道断面形式、基土层保温、防水和换填等方面,提出了适应和削减冻胀的一系列经济实用的工程技术措施。
The frost heaving damage of canal lining is common for the large and middle scale irrigation area in cold area and has great damage to canal and irrigation area operation for the area with the high groundwater level.Through analysis of the frost heaving mechanism and project experience for many years,the paper puts forward a series of economical and practical technical measures to adopt and decrease frost heaving from many aspects such as section form of canal,thermal insulation of soil foundation,waterproof and changing and filling and so on.
