| 摘 要： | 本文以密云县石城镇贾峪东沟为实验模拟原型,通过小型水槽实验,对沟床纵坡降与泥石流堆积形态的关系进行实验研究。通过实验,获取了不同沟床纵坡降泥石流的堆积长度、宽度、厚度、堆积面积以及堆积形态比方面的数据。通过对实验数据分析,得出沟床纵坡降分别与堆积长度、宽度、厚度、面积与堆积形态比的回归方程及相关系数,为泥石流危险性或危害性评价提供参考。

| Abstract: | Jiayu eastern ditch is situated at Shicheng Town,Miyun County,which is taken as an example of simulating prototype.The experimental research on the relation between deposition feature of debris flow and longitudinal slope declination of gully bed was carried out by simulation of small flume experiment.The data of length,width,thickness,area and shape ratio of accumulation of debris flow of different gully beds was obtained. By analyzing experimental data,the regression equation and correlation coefficient b... |
