摘　　要：在内蒙古河套灌区首次采用固化土衬砌渠道作为渠道防渗抗冻的新技术。简要说明土壤固化剂原理,通过室内试验得出固化土性能,通过施工实践总结出固化土施工工艺。应用已有和自行开发的土壤固化剂制作固化板,进行防渗、抗冻观测试验,对冻深、冻胀量、防渗效果和工程造价作出定量结论,已在大型灌区田间渠道衬砌中推广应用。Lining canal with solidified soil was used as a new technique for seepage control and frost heaving control of irrigation canal in Inner Mongolia Hetao Irrigation District for the first time.The seepage control and frost heaving control principles of solidified soil were explained briefly.The physical properties of solidified soil were obtained through laboratory test and the solidified Soil construction technique was summarized on basis of its construction practice.The frost depth,frost heaving amount,seepage control performance and construction cost of existing and self-developed solidified soil slab made from soil solidifying agent were quantified through frost heaving control and seepage control observations and were applied in the reconstruction project for water-saving in the large-scale Irrigation district.
