中文摘要：

测量碎片流动的内部速度为碎片流动动力学研究是很重要的，设计碎片流动控制工作。然而，为因为碎片流动过程的破坏力量，测量内部速度没有适当方法。在这篇论文，我们由使用在速度和运动压力之间的关系，由表面速度和表面描述了运动压力数据处理这个问题。运动压力是影响压力和静态的压力的差别。前者被在采样节在流动方向安装的力量传感器检测。观察证明静态的压力能被简单地用水密度代替碎片流动密度为静态的水压力用公式计算。我们描述在用从七实验室斜槽的数据的运动压力试验的表面速度和表面之间的关系。它与为单个阶段流动的关系一致，它是 Pitot 试管的测量原则。

英文摘要：

Measuring the internal velocity of debris flows is very important for debris flow dynamics research and designing debris flow control works. However, there is no appropriate method for measuring the internal velocity because of the destructive power of debris flow process. In this paper, we address this problem by using the relationship between velocity and kinetic pressure, as described by surface velocity and surface kinetic pressure data. Kinetic pressure is the difference of impact pressure and static pressure. The former is detected by force sensors installed in the flow direction at the sampling section. Observations show that static pressure can be computed using the formula for static water pressure by simply substituting water density for debris flow density. We describe the relationship between surface velocity and surface kinetic pressure using data from seven laboratory flume experiments. It is consistent with the relationship for single phase flow, which is the measurement principle of the Pitot tube.
