Other AbstractDebris flow cumulate stone roundness is an important base for debris flow frequency identification. This is a positive effect on the in-depth study of the frequency of outbreaks of debris flow. We selected 34 different outbreak frequency of debris flow as a samples,used the psephicity method proposed by professor POWERS to determine the debris flow stone roundness value (y) to build a relationship between debris flows,and studied the relationship between the discovery of debris flow stone psephicity and outbreak frequency. For flood debris flow deposition,the rock roundness value ranges as 0.41≤y≤0.59,the degree of roundness is grinding circle,sub circle; low frequency debris flow deposition rock roundness value ranges as 0.3≤y≤0.41,the degree of roundness is sub circle; in high frequency debris flow deposits rocks roundness values ranges as 0.21≤y≤0.3,the degree of roundness is angular,sub angular. Comprehensive study found that the frequency and the accumulation of debris flow in rock psephicity is proportional,and their correlation is significant. The research results can be applied to the typical debris flow gully debris flow frequency identification,and identification results are consistent with field inquisitional results.
