摘要
泥石流堆积坡度主要受流路地形坡度和流体性质的影响，所以必须考虑同级水系流路地形坡度才有可比性。试验研究表明，泥石流堆积扇的淤积比降比最大值为４；粘性泥石流堆积坡度预测模式为α＝７．０２Ｑｕ８．０５ｅｘｐ（３．０４Ｑｕ６．４３ｌｎＣｖ），当ｔ＝０．０１时达到极显著水平，其９５％的置信区间为０．７０５＜Ｐ＜０．９３９。这些研究为泥石流防治工程中堆积坡度的预测提供了重要参数。
Deposit slope of debris flow are majorly controlled by lower-running landform slope and flow characteristics. It is necessary to think over landform slope of the samegrade of strtam-system, so that it can have comparison with each other. Experimental research indicated that the largest value on ratio of landform to deposit slope is four; predicting deposit model of viscous debris flow is a= 7.02Q exp (3.04 Q Ln Cv). When t=0.01,the experimental data have reached the relatively notablest level, the 95% believable ranges are 0.705<ρ<0.939. These researches will provide inmportant parameter in controlled prevention of debris flow for predicting deposit slope.
