中文摘要：

陡峻的地形、大量松散的固体物质条件、短时强降水构成了泥石流发生的三大要素，同时也是直接影响泥石流堆积数量与规模的重要因素。通过改变泥石流流通区、堆积区不同区段的坡度对非均质泥石流堆积过程进行室内模拟实验，探究流通区、堆积区不同坡度条件下非均质泥石流的堆积厚度、面积等特征值的变化特征，即随着流通区坡度增大，泥石流堆积厚度减少，而堆积面积和体积均增大，并进一步建立了不同坡度因子与泥石流堆积数量之间的关系，为预测不同坡度地形条件下泥石流堆积规模提供科学依据。

英文摘要：

Basic conditions of debris flow formation generally include steep slope, loose solid particle and heavy rain, which are influenced on the deposition of non-homogeneous debris flow. A series of deposition simulation experiments for non-homogeneous debris flow were carried out in lab. By means of the changing of hydraulic gradient and specific weight gravity, the influences of gradients on the deposition of non-homo- geneous debris flow were studied. Furthermore, the meaning relations between the deposition and gradients were established. The results above are significant for predicting deposition scales and disasters control proj- ect for debris flow.
