高坡降小流域泥石流特性与治理设计研究

Research on Debris Flow Characteristics and Control Design of High Grade Small Watershed

泥石流具有爆发突然、摧毁力强等特点,对工程建设及运行期的影响危害巨大,工程建设前期研究及运行期对工程建设区典型中~大型泥石流沟研究详致,并采取相应的措施,但对高坡降小流域泥石流特性等研究较缺乏,近年来水电、铁路等工程建设遭受小流域泥石流影响较突出,文章以高坡降小流域泥石流特性、危害进行研究,并提出相应的对策。

Debris flow has the characteristics of broke out suddenly and destroy force strong,influence on engineering construction and operation period of great harm. Prior to the construction of the project research and operation period of engineering looks remarkably typical ~ large debris flow gully study in detailed,and take corresponding measures,but the lack of research on high grade debris flow characteristics of small watershed. In recent years,water and electricity and railway engineering construction by small watershed mud-rock flow is more outstanding,based on high grade debris flow characteristics of small watershed,hazard were studied,And puts forward relative countermeasures.
