AB  - With the intensification of warming and humidification in the Loess Plateau region, the mechanism of deformation and instability of saline loess under the influence of humidity and rainfall is unknown, which has become a new challenge in the field of geological hazards. This article takes the loess in Lanzhou area as the research object, and controls the adsorption suction by saturated salt solution vapor equilibrium method and the capillary suction by pressure film instrument to obtain the soil water characteristic curve of saline loess under wide suction. Combined with triaxial shear test, the mechanical behavior evolution of unsaturated loess under the influence of adsorption suction (representing humidity), capillary suction (representing free water) and solute suction (representing salt) is studied.
