AbstractThe ground condition of catastrophic landslides influenced their movement criteria. It was important engineering significance to assess the disaster and forecast buried area by the influential laws of ground conditions. According to data and field investigation of recent catastrophic landslides, during the analysis, the evaluation criteria of landslide movement were the landslide apparent coefficient of friction and ground block coefficient. The influential laws of landslide movement criteria were analyzed which 3 influential factors of ground were considered including ground gradient (a), constraints angle of slope foot (theta) and ground type (X). Landslide volumes range from 10(6) to 10(7)m(3), the influence factors of landslide apparent coefficient of friction and block coefficient were ground type (X), ground gradient (a), constraints angle of slope foot (theta) in turn. But the volume range more than 10(7)m(3), the influence factors of apparent coefficient of friction and block coefficient were ground gradient (a), ground type (X), constraints angle of slope foot (theta) in turn. The ground gradient (a) and ground type (X) were dominated factors of landslide apparent coefficient of friction and the constraints angle of slope foot (theta) was weak. All factors markedly influenced on the block coefficient. The results showed that, to the different landslide volume, there was significant difference that the ground influenced on the landslide apparent coefficient of friction and block coefficient.
