不同频率下的泥石流体特征数值计算方法研究——以大寨沟流域为例
- Title:
- Calculation of Characteristics Factors of Debris Flow Under Different Frequency——Take Dazhaigou Valley as an Example
- Keywords:
- debris flow; characteristics Factors; discharge; current velocity; scale
- 分类号:
- P624.23
- 摘要:
- 在泥石流定量研究中,泥石流流量、流速、泥石流规模是泥石流体最重要的特征值.能比较准确的确定泥石流这些特征数值既是泥石流计算中的关键问题,也是泥石流防治工程设计研究中的重要因素.利用雨洪法,首先比较一种或两种水文学的计算方法,择优来计算暴雨与洪水特征数值,然后利用暴雨与洪水特征数值来推算泥石流体各种特征数值.比如用暴雨洪峰流量以及配方法来计算泥石流流量,利用洪水总量来推算泥石流规模.
- Abstract:
- In metered research of debris flow,the debris flow discharge,current velocity,the debris flow scale are the most important characteristic factors in the debris flow.Calculating characteristics factors accurately is not only the key problem within the debris flow calculation,but also the important factor of research on debris flow’s prevention and cure.Rain-storm and flood method is used,making use of one or two kinds of calculation method to calculate rain-storm and the flood characteristic factors,then making use of the rain-storm and the flood characteristic factors to reckon various characteristic factors of the debris flow.For example,to calculate the debris flow discharge with the rain-storm biggest discharge and the formulation methods,or make use of the flood total amount to reckon the debris flow scale.
