摘　　要：为了研究灌溉管道浅埋方式,在总结研究现状的基础上,首先分析了不同情况下的管道受力情况,以及管道的开裂方式,然后估算了在管道工作的最不利情况下管道内部冰胀压力大小,分析了冻土的冻胀和融沉作用影响因素,最后给出了浅埋防冻的具体措施和建议,包括管沟换填、安装伸缩节和排空管道等。一些地区的现有经验表明,采取相应的措施后,灌溉管道浅埋可行。In order to study the way of the irrigation pipes buried in a shallow layer, the pipe stress under different conditions and the cracking way of pipeline were analyzed based on the related research status. The ice stresses of pipeline were estimated in the worst working situa- tion and the factors affecting the frost heave and thaw settlement process of frozen ground were listed in the context. Finally specific measures were given to protect the pipeline buried in a shallow layer. These measures included emptying pipes after irrigation, installing expansion joints and the trench replacement. Existing experience shows that burring irrigation pipes in a shallow layer is feasible after taking corresponding measures in Northeast China.
