国外泥石流机理模型综述

An Overview of Foreign Debris Flow Mechanism Models

综述了国外与机理有关的几个主要泥石流运动模型。建议近期泥石流运动机理研究宜着重厘定各类模型的适用范围和比较它们的应用结果,并进一步简化现有的机理模型,为泥石流防治工程提供具有一定理论基础和科学依据的流速、流量和冲击力等关键设计参数。与泥石流机理密切相关的预测预报,宜着重于泥石流的中长期预测和预警报,重点突破泥石流规模和发生频率相互关系的问题。

This paper provides an overview of the most important foreign debris flow mechanism models It is suggested that the present studies on debris flow models should focus on defining the suitability of various mechanism models, comparing their application results and simplifying the existing models, so as to provide critical parameters of debris flow velocity, discharge and impact force for design of debris flow control engineering For the prediction of debris flows, which is closely related with debris flow mechanism, the mediumterm prediction and early warning should be emphasized and the main efforts should be put into the study on the relation between the scale of debris flow and occurrence frequency
