Abstract:: According to the results of previous studies and field investigations and preliminary tests,the affected factors of surge volume concentration of debris flow are analyzed and the non-dimensional relationship is duduced.In addition,the multi-analysis regression equation is established according to experiment results.The results also indicated that sediment volume concentration ratio is subject to incision density(Σb/B),the relative width of incision(b/d₉₅) and relative depth of incision(h_s/H_e),the impact showed a positive correlation relationship at the same flume slope and sediment size distribution.
