摘　　要：以关家川沟泥石流为例,在没有泥石流动力学特征实测资料的情况下,在地质调查的基础上,采用推理公式,计算关家川沟的泥石流流速、流量、一次泥石流总量及冲击力等特征值;最后结合泥石流一次固体物质总量,对泥石流对工程的影响作出评价。此方法可为在没有泥石流动力学特征实测资料的情况下分析泥石流对工程的影响提供借鉴。Taking the debris flow of Guanjiachuan Gully as example and without actual measured data of dynamics characteristics of debris flow, this paper applies inferential equations to calculate the characteristic values of the velocity and discharge of debris flow, total amount and impact force, based on geological investigation. Finally the debris flow influence on engineering was evaluated in combination with once solid material gross. This method can be used for reference to analyze the influence of debris flow on project without actual measured data of dynamics characteristics of debris flow.
