摘　　要：本文从寒区灌区引水渠道建设过程中遇到的实际问题出发,以实际工程为例,从基础抗冻、基坑稳定性、渠道防渗效果,以及渠道自身强度四个方面出发,介绍了引水渠道设计过程中的防渗设计方案,使用数值模拟方法对基坑开挖后的稳定性进行验算。结合工程技术要求及经济效益选取渠道衬砌材料,本设计方案和设计方法可为类似的工程提供参考。Aiming at the practical problems encountered in the construction of diversion canal in cold irrigation area, the designing schemes of seepage prevention during the design process of diversion channel are firstly introduced from the point of the anti-freezing of foundation, foundation pit stability, anti-seepage effect of canal and canal strength. The stability of foundation pit after excavation is then checked by numerical simulation method and the selection of channel lining material have considered the actual conditions of the engineering combined with economic benefit. Finally, the proposed design scheme and design method can provide reference for similar projects.
