The Impact of Particle Size on Failure Mode of Sandy Debris Flow

Abstract:

Article Preview

Based on self-designed flume model device of sandy debris flow, the experiments under artificial rainfall were carried out to study the debris flow failure mode of different grain size. By using the Digital Photogrammetry for Deformation Measurement GEODOG, the failure process and displacement field of sandy debris flow were analyzed. The studies indicate that the failure mode of medium sand is Retrogressive Toe Sliding as the movement of particle concentrated on sand anterior of flume model. The failure mode of fine sand is Flow-slide Failure as the movement of particle concentrated on sand in the rear of flume model.
