Abstract

Debris-flow impact force exhibits strong randomness due to irregular shape and motion of coarse particles in the flow. In order to examine the influence of grain size on the impact force and its characteristics of random distribution，seven groups tests of debris-flow impact forces were carried out by large-scale flume in the Dongchuan station，Chinese Academy of Sciences. The material used in the tests originates from Jiangjia Ravine′s debris-flow deposition and the grain size is up to 8 cm. The experimental results indicate：the dimensionless impact force of debris-flow increases with the dimensionless maximum size of coarse particles，and there is a good exponential empirical relationship between them. The Log-Logistic probability density function is the best one to describe the distribution of the impact force among six probability density functions. The values of the Log-Logistic function′s scale and shape parameters increase with the dimensionless maximum size of coarse particles，showing the logarithmic empirical relationships between the parameters and size.

Key words： engineering geology diluted debris flow coarse particle impact force log-logistic function random relationship
