Other Abstract



A large-scale colluvium model test was conducted on rainfall induced slope failure to investigate the laws of the seepage, deformation and failure of colluvium slope under rainfall conditions. Acoustic emission as a criterion of warning was discussed. Results showed that after the wetting front has reached the corresponding measuring point, the volume fraction of water increases continually, and the water level begins to increase untill the volume fraction of water reaches its peak value. The displacement at the top of the slope is large and is small at the toe, and the increase of the displacement of the slope has an acceleration process before failure occurs. The tilt angle increases suddenly when failure occurs. The acoustic emission accounts increase slowly at first and sharply afterwards. Slope failure is strongly linked to surface runoff and fine particle migration.
