 Located within the province of Sichuan, Jiaojigou is a first class branch along the left bank of Daduhe River, historical mud-rock fall activity was obvious and the roads and villages were broken by the mud-rock fall. Solo channel mud-rock fall fatalness evaluation was adopted in combination with remote sensing interpretation and field investigation; the authors conducted the analysis on the formation conditions, types and fatalness of the mud-rock fall. Based on the occurrence characteristics of the mud-rock fall in Jiaojigou, the authors analyzed the effect of the mud-rock fall engineering. It was concluded that Jiaojigou was restricted to low frequency and medium liable mud-rock fall, of mild influence to the reservoirs both upper and lower reaches of the Daduhe River.
