摘要
泥石流冲击力是许多工程结构破坏的主要因素，但泥石流冲击力的计算还未有适当的方式。本文通过对泥石流冲击力实测资料的分析和处理，得到了泥石流冲击力频谱特性曲线，并利用此曲线阐明了泥石流工程结构设计中如何计算冲击力的问题。
The impact force of debris folw is the main factor of the failure of engineering strucures.But there is no proper method to calculate the force.This paper analyzes and proccesses the data of impact force collected from the field,and obtains the frequency curves of impact force of debris flow.How to calculate the impact force in engineering design by using these curves is explained.
