Experimental study on the shear behavior of saw-toothed ice-rich debris–rock interface: effects of undulation, ice content, normal stress, and temperature
Direct shear tests have been extensively conducted on undulated soil-structure interfaces, but there has been limited research on ice-rich debris-rock interface (IDRI). Glacier bedrock often experiences abrasi...

Failure mechanism of the slope containing coarse particle enrichment zones located at the soil–rock interface under the heavy rainfall
Internal erosion caused by seepage at the soil–rock interface with local coarse particle enrichment zones (CPEZ) is a significant factor contributing to geological disasters during rainfall events. The mechani...
