| 摘 要： | 在综合分析西北季节性冻土地区滑坡发生时间规律和危险斜坡变形动态规律的基础上，提出季节性冻融作用产生的冻结滞水效应可使斜坡区地下水富集，土体软化范围扩大瞌 水压力增大，是本区滑坡发育的一种重要外动力因素，并对其作用机理和发生条件进行了论述。

| Abstract: | It is pointed out that effect of water entrapment due to seasonal freezing can enrich groundwater, expand the range of softening soil and enhance static and dynamic water pressures in soil This is found from a comprehensive analysis on the occurring time of landslide and the deformation mechanisms of dangerous slope It is an important external dynamic factor for landslides occurring in Northwest China Besides, the occurring conditions and mechanisms of this landslide are also discussed in this paper |

| Keywords: | seasonal freezing- thawing effect of water entrapment due to seasonal freezing landslide factor |
