- Abstract:
-
Three kinds of sandpiles with size distribution which professed fractal characters designed as the generalization models of the mountain disasters,their dynamics behavior are researched by experiment.The results showed self-organize criticality.According to the current geomorphology characteristics,the evolution characters of mountain hazards are analyzed further,all of them have the characteristics of power-law and self-organized criticality.The improved rescaled range analysis was introduced into the analysis and treatment on the precursor monitoring date of the debris flow disaster,Hurst exponent H is calculated,which could forecast the occurrence of great scale debris flow by abnormal change of value H Jiangjiagou debris flow in Yunnan as example.
