strength of sandstone increased with the increase of strain rate. The water-saturated rock specimens showed stronger rate dependence than the dry ones, but the loading rate sensitivity of thermally...-physical mechanisms of sandstone under different loading rate conditions after heat treatment were further discussed. Key words: sandstone; dynamic tensile strength; hydro-thermal coupling damage......
