摘要
采用重正化群方法算出三维自由渗流模型的渗流阀值 ,在此基础上提出三维具有自相似性质的渗流模型。
Percolation threshold of free percolation 3 D model is calculated by renormalization group method On the basis of this, a 3 D model of self similar percolation is developed With the model, we explain why the other side of river is earlier to break than the other places of the dam in many real cases Moreover, in the terms of the situation changes of debris flow dam after the river is blocked up by debris flow, the mechanism of debris flow dam break is discussed
