Abstract:
Motor process of oversize mud-rock flow in Yajiageng River of Eastern Gongga Mountain on August 11, 2005 was described; kinetic characteristics of mud-rock flow were calculated quantificationally with the means of field survey, and was used to simulate the motor process of mud-rock flow in order to find the mechanism of oversize mud-rock flow in Yajiageng River. The results showed that formation of oversize mud-rock flow in Yajiageng River was directly related to the rainfall; mud-rock flow in tributary ditch of Yajiageng River meantime happened, and caused that the flow in the master river was huge; the eruptive period was 18-21 years according to the history of mud-rock flow in Yajiageng River; because loose material was plentiful, rainfall and water were rich and terrain was precipitous, oversize mud-rock flow in Yajiageng River could happen again.
