泥石流流速公式探讨

THE DISCUSSION ON FORMULAE FORCALCULATING VELOCITY OF THE DEBRIS FLOW

本文首先对常用的泥石流流速计算公式存在的问题进行了分析，然后根据观测数据，建立了精度较高的计算泥石流流速的回归方程。由于参加统计的资料参数变化范围大，地域广，迭用的自变量少且可操作性强，故新公式具有推广价值。

The paper discussed the problems which prensent in the formulae generally used for the calculation of current velocity of debris flow and find a solution for the problems.Then based on the observed data (153 groups of viscous debris flow, 31 groups of rarefied debris flow), a regression equation for calculating the current velocity of viscous and raiefied debris flow with a higher precision is established. Due to the Parameters included in statistical data change with a wide scope and extensive area less independent variables are chosen, so the new formulae with a maneuver-ability are worthy to be popularized.
