Research about the influence of amount of debris on Changbai Mountain debris flow

Debris flow of Changbai Mountain was selected as the object of this research. We carried out soil test using different samples in Changbai Mountain. Then built the simulation test platform to simulate the formation of debris flow,and discuss the variation of accumulation zone with the different amount of debris. Do the fitting about simulate thickness,length,width,area,spread angle with the amount of debris. The result showed that with the increase of debris in provenance section,the data above increased in different degree.
