Slide Accelerated by Water Entrapment Due to Seasonal Freezing

Wu Weijiang (Geological Hazards Institute, Gansu Academy of Sciences, Lanzhou 730000)  
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
