【摘要】 以泥沙运动和泥石流形成的理论力学为基础,重点论证了固相松散堆积物构成准泥石流体的条件,进行了相应的起动需水量模拟实验.通过准泥石流体屈服方程的建立,做出了武都地区泥石流沟道中准泥石流体起动数学模型,为该地区预报泥石流灾害发生发展提供了一定的科学依据.更多还原

【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.更多还原
