摘　　要：渠道是构成各类型灌区的重要基础,随着使用时间增长,很多老旧干渠遭受严重冻胀破坏,必须进行改造。以喀什噶尔河灌区干渠改造工程为例,通过分析冻胀破坏因素、分析力学模型确定渠道最佳断面形式,并利用置换法对存在冻胀危险渠基土进行彻底处理,从根本上解决干渠冻胀破坏问题,本项目取得的成功经验可为该地区类似工程提供技术参考。Channels are an important basis for all types of irrigation districts. As the use of time increases, many old canals suffer severe frost heaving damage and must be modified. Taking the reconstruction project of the main channel of the Kashgar River irrigation area as an example, the optimal section form of the channel is determined by analyzing the factors of frost heaving damage and analyzing the mechanical model, and the replacement method is used to thoroughly treat the base soil with frost heaving danger, and the main channel is fundamentally solved. The problem of frost heaving damage, the successful experience of this project can provide a technical reference for similar projects in the region.
