Water is the triggering factor of landslides usually, and using the numerical method to simulate landslides considering liquid bridge force will help to improve the rationality of the calculation results. In order to study the kinetic characteristics of water-bearing deposition landslide, the Linear Cohesion contact model was proposed to simulate the loose deposition landslides under wet condition. A numerical model of water-bearing deposition landslide flume was established by the discrete element program EDEM 2017 to simulate the whole sliding process from instability to sliding to deposit. The results showed that energy density k was the key parameter of Linear Cohesion model in the simulation of water-bearing deposition landslide. When k＜5000 J/m3, with the increase of energy density, the fluidity of deposition sliding process became smaller, and the maximum average velocity and maximum kinetic energy increased. When k≥5000 J/m3, the sliding characteristics of water-bearing deposition changed insignificantly. The structure of wet granular deposition with small energy density was easily to be destroyed during the sliding process, the fluidity of the granular groups formed in the process was stronger and the sliding distance was longer, which enlarged the impact scope of landslide disaster. These results are helpful for the prediction and evaluation of similar water-bearing deposition landslide disasters in the future.
