摘要
衬砌渠道冻胀破坏多年来一直影响着宁夏引黄灌区渠道的使用年限和安全运行,制约着灌区发展。通过大量的试验数据对引起灌区混凝土衬砌渠道冻胀破坏的渠床土质、土体密度、气温、地温、冻土深度、冻胀量、基土水份、地下水位等因素进行研究分析,研究衬砌渠道冻胀破坏机理、各影响因素与冻胀破坏的关系,为灌区续建配套和节水工程改造设计与建设提供技术依据。
The canal has been affecting the service life and safe operation of Ningxia Irrigation Area. In this paper, through a large number of experiment data , an analysis is made of concrete lining irrigation channels the canal bed soil caused by frost damage, soil density, temperature, ground temperature, permafrost depth, frost heave, base soil moisture, groundwater and other factors. Research is done on frozen canal failure mechanism, the relationship between the influencing factors and frost damage Technical support has been provided for the design and construction of water-saving irrigation areas.
