ABSTRACT
Loess is a special soil, widely distributed in our country, and is one of a sediments in quaternary period, mainly located in the arid and semi-arid regions, normal is non-saturated status, moisture content plays an important role in the shear strength characteristics, effect of temperature on the water and thus also affect the shear strength characteristics of loess, loess engineering in cold regions has been great development in recent years, the freeze-thaw deterioration on loess shear strength is an important research topic in permafrost Mechanics and Engineering.
