寒冷地区渠道混凝土冻胀破坏的原因及防治措施研究

Causes and prevention measures of frost heaving damage of channel concrete in cold area

文章以新疆北疆某灌区渠道工程为研究对象,以寒区混凝土渠道冻胀破坏为主要研究问题,通过基土含水量、土质类型、地下水位等因素解释了常见的渠道冻胀破坏的机理,以渠道冻结测点数据为关键点,基于有限元分析,证实了与实际情况相符,同时针对上述影响冻胀破坏的因素,提出了基土置换、阻断法等防治措施。

This paper takes the channel project of a irrigation district in northern Xinjiang as the research object,takes the frost heaving failure of concrete channel in cold area as the main research problem,explains the common mechanism of channel frost heaving failure through the factors of water content,soil type and groundwater level,and takes the data of channel freezing measuring point as the key point.Based on finite element analysis,it is proved to be consistent with the actual situation.At the same time,in view of the above factors affecting frost heave damage,the prevention measures such as base soil replacement and blocking are put forward.
