TXT-tool 4.086-1.2: Shallow Landslides and Plant Protection in Seasonal Frozen Regions

Chapter

Abstract

In high-latitude frozen regions of Northeast China, soil cutting slopes often trigger shallow landslides. These shallow landslide are of a unique type and the root cause of it is the seasonal freeze-thaw behavior. In autumn, shallow slopes have high moisture content and get frozen quickly. In spring these layers thaw slowly and become impermeable layer, so thawing water was hampered by frozen layer, resulting in the water content increasing rapidly in the interface between thawed layer and impermeable layer, and then causing the partial or complete sliding of the shallow layer of the slope along the slip band due to gravity. Traditional geotechnical countermeasure approach often may not be effective for the slope protection. We select the method of planting shrubs. Plant roots could reduce soil moisture by absorbing water and increasing transpiration, as well as roots into the slope form anchor system and strengthen the shear strength of soil body, preventing the shallow landslides.
