摘要
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 between longitudinal slope declination of gully bed and length, width, thickness, area and shape ratio of accumulation of debris flow were presented, which provide reference for hazard assessment of debris flow.
