泥石流洪峰流量的研究与计算

Study and Calculation of Peak Discharge of Debris Flow

泥石流洪峰流量是泥石流的重要特征值,它反映了泥石流的规模、强度及流体性质,决定着防治工程建筑物的结构及尺寸,是泥石流研究的重要内容之一。

Peak discharge is an important characteristic value of the debris flow, which represents the scale, intensity and fluid property of debris flow and also determines the structure and size of the prevention projects, Experts of debris flow at home and aboard always pay close attention to the method of calculation for the peak discharge. The researchers not only calculate the value by using field observed data in corporation with the morphological information obtained through field investigation but also use the method of calculation by d irections, synthetical cause of formation or statistics etc. The paper expounds the advantages and defects of the above-mentioned methods, and also introduces several equations for calculating the peak discharge of different types of debris flow.
