Landslide debris flows likely do great damage to communal facilities in mountain area by wide range of sliding motion and deposit, which have close relation with the features of source area and sliding path. Based on physical model experiments in this study, the interaction between debris flows and adjacent terrain has been simulated to investigate the sliding motion and deposit characteristics with different particle size distributions and moisture contents of source debris flows. Distinct deposit characteristics including fingering deposits, inverse grading and transverse ridges could be observed from the tests. With the particle size increasing, both debris flow travel distance and deposit width increase, while the maximum deposit height gradually decreases. With the moisture content increasing, both debris flow travel distance and deposit width initially increase then decrease. Besides, the debris flow velocity is faster with larger particle sizes but slower with higher moisture content. Energy loss during debris flow sliding motion is primarily caused by friction and collision. Analysis according to experiments show that an increase in moisture content would amplify the loss of frictional energy but diminish the collision energy, but both particle size distribution and moisture content have relatively minor influence on total energy loss.
