| Abstract: | Based upon the theoretical mechanics of forming debris flow and silt movement,the paper proves mainly deposite conditions to form para-debris flowing body,and the simulated test of requiring water to start debris flow is also discussed.By setting up the yield equation of the pare-debris flowing body,the mathematical model of starting para-debris flow has been finished in debris flow valley of Wudu district,Gansu province.The model could be used to provide scientific basis for forecasting,the calamity of debris flow in the region. |
