Abstract: To study the tensile strength characteristics of mountain glacier ice,150 remolded ice samples with different debris contents(0,5%,10%,15%, and 20%) were prepared. The Brazil split test was used to study the tensile strength of ice under different temperatures (-3 ℃,-5 ℃,-10 ℃,-15 ℃, and -20 ℃) and loading rates(0.04 mm·s^-1 and 0.1 mm·s^-1). The results show that ice samples initiated cracks, expanded, and underwent through-thickness failure along the loading direction. The characteristics of the rupture surface are related to the debris content and temperature. The higher the debris content and the lower the temperature, the more brittle the ice is. The tensile strength of pure ice decreases linearly with temperature; the tensile strength of debris ice rises first and then decreases with temperature, reaching the maximum value at about -10 ℃. The tensile strength of ice increased with the increase of debris content, with 20% debris content reaching 1.82 times that of pure ice. When the temperature is low and the debris content is less, the greater the loading rate, the higher the tensile strength. The results provide a theoretical basis for revealing the mechanism of cracking and disaster of mountain glacier ice.
