中文摘要：

水库浸没是由于水库蓄水或其他人类工程活动，促使浅层地下水位上升，引起各类灾害的一种现象。水库浸没的评价一般依据当地潜水回水位埋深与地下水临界埋深之间的关系确定。由于特殊的低温及冻融作用，与非寒区相比，寒区水库浸没形成机理相对复杂，因此如何合理确定寒区地下水临界埋深对水库浸没的评价尤为重要。集中研究寒区水库浸没地下水埋深，调查一处典型区域的浸没情况。为寒区水库浸没评价的分析和计算提供一定的数据和方法参考。

英文摘要：

Reservoir immersion is geological hazard caused by the groundwater level rise which may from reservoir water store and humun being engineering activities. Generally, according to the relationship between phreatic water level and the depth of groundwater buried, evaluation of reservoir immersion is determined. Compared with the non-cold regions, because of low temperature and freezing-thawing action in cold region, formation mechanism of immersion is complex. Therefore, how to reasonably determine the buried depth of groundwater is critical to evaluation of reservoir immersion in cold region. In order to research on buried depth of groundwater in cold region, investigation of the immersion is made in typical area. This paper provides corresponding reference for the evaluation and analysis of immersion in cold area.
