| 摘 要： | 采用文献「１」中提出的阵性泥石流运动与堆积的欧拉－拉格朗日模型，模拟了阵性泥石流的运动过程的堆积形态，得出了与地学研究中观测结果较为一致的认识，文中针对影响阵性泥石关键条件，重点通过改变密度、坡度和各阵泥石流的时间间隔等参数，分析了这些参数变化对泥石流运动及规程规律的影响，提出了简化分析整个阵性泥石流的条件，研究表明，应用经试验资料验证的数学模拟不但可以方便，快捷地定量描述阵性泥石流的一般特征，而

| Abstract: | Based on the conceptual two-flow model and PIC numerical solution method developed in the companion paper,the present paper further investigate the model application in simulation of the typical debris flows.The model validation was carried out with the experimental data obtained by other investigators at Dongchuan Debris Flow Observation and Research Station in Yunnan Province.Predictions were made in terms of the main controlling facetors including the channel slope,flow density and time interval between two blasts of debris flows.The predicted results could well reflect the observations reported by the geographers and sedimentologists. |
