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...
