谈季节性冻土区给排水系统冻害及防治措施

Frozen Injury and Prevention Measures of Water Supply and Drainage System in Seasonal Frozen Area

对埋置在冻土层内的管道因周围土体力学特征的改变及管道自身的冻结危害进行了分析,列举了管道系统易发生的常见冻害,并且对其发生机理进行了系统阐述。针对不同的冻害类型,提出了多种有效的防冻解决措施以及保温措施,为季节性冻土区给排水系统的设计及施工提供了依据。

Based on the buried pipeline in permafrost layer due to change of mechanical characteristics of frozen soil around the pipeline and its hazard analysis, the common injury prone to pipeline systemand the mechanism were systematically expounded.According to the different types of damage,various effective anti-freezing measuresand insulation measures are put forward, which provide the basis for the design and construction of water supply and drainage system in seasonal frozen area.
