Abstract

The fundamental characters and failure mechanism of the landslides related to freeze-thaw action are introduced in this paper. Monitoring of the ground temperature and the pore water pressure at the landslide located at the side of the Heifangtai loess platform, Gansu province suggested freezing can build an underground reservoir at the deep position within the slope in frozen season and then after thawing can release the water out in warmer season. Consequently, it produces a high pore water pressure in winter as well as a high water gradient in spring as the water released. Both the static high pore water pressure and the high water gradient will decrease the slope stability and trigger landslides.
