中文摘要	泥石流危险范围的模型实验预测旨在确定一次泥石流可能堆积泛滥的最大范围.通过泥石流不同冲出量、堆积区坡度和容重的31次模型实验,获取了泥石流堆积面积.最大堆积长度、宽度和厚度的实验数据.采用量纲分析方法,建立了一次泥石流危险范围的预测模型,并由实验资料确定了模型的修正系数.在云南和甘肃的应用实践表明,预测模型精度高,适用范围广,可在我国泥石流危险范围预测预报中使用.
英文摘要	The model experiment forecast on the risk range of debris flow is to determine the possi-ble maximun range of a debris flow accumulation.Through the 31 times of modee experi-ments with different runouts,depositional gradients and unit weights,the data of the accumu-lative area,the maximum accumulative length,width and thickness are obtained.Applyingthe dimensional analysis,the model experiment forecast on the risk range of a debris flow isestablished,and based on the experimental data,the revisionary coefficient of the forecastmodel are gained.Therefore,using the model,and on the basis of the three parameters—adebris flow runout,depositional gradient and unit weight,the possible maximum accumula-tive area,length and thickness can be quantitatively forecasted.According to the plane shaperegulation of the risk range,when the depositional gradient is 1～5 degrees,the viscous de-bris flow fan is circle;when the depositional gradient is 6～10 degrees,the viscous debrisflow fan is ellipse.The torrential debris flow fan is always rectangle.The average relativeerror of the model is 8.34%.and its applications in the southwestern and northwestern Chinahave good results,which can be further practised in the forecast on the risk range of a debrisflow.
