Abstract: There are more than 4700 debris flow hazards along the main traffic lines of railway and highway in western China, which account for 70 percent of the debris flows along traffic lines in the whole country. Debris flows are distributed extensively, frequently cause serious damage and losses in traffic construction in western China region. A large number of studies and investigations, six measures for controlling debris flows in the paper, which are correctly distinguishing debris flow gullies and their development process strictly choosing suitable route, engineering design in donsideration of the characteristics of debris flow, rising survey and design level for mitigating and preventing disaster,and carrying out debris flow prevention testing and demonstrating works.
