摘要
The energy flow controls many transitions that happen on the land, especially in process of debris flow, the energy attenuation is the reason and driving force. This paper base on energy, according to represent the axiom and application of energy-line model, explain the calculation formula of energy consumption, introduce a new viewpoint of debris flow mitigation. The new concept is that we can start with controlling energy decay, through reducing the moving mass and enhance the external and internal friction, adopt a series of measures to provide reference for preventing and curing the influence of debris flow.
