Current Velocity Calculation of Debris Flow Based on Excess-Height in Bend
-
摘要: 泥石流流速是难以实测和准确推算的重要参数。在分析既有各类弯道超高计算公式的基础上，探讨适用于各类泥石流的弯道超高计算模式，进而改进基于弯道超高的粘性泥石流、稀性泥石流和泥流的流速计算公式，用实例加以验证。Abstract: The current velocity is an important parameter of debris flow, and it is more difficulty to be measured and calculated. Based on analysis to every known calculating formulas of excess-height in bend, the calculating models of excess-height in bend m every debris flows are explored. Further, the formulas calculating current velocity of mudflow, dilute and viscous debris flows based on excess-height in bend are improved, and are tested with real examples.
