摘要
本文通过对宝成铁路沿线泥石流沉积物粒度资料绘制的三角图、散布图、CM图、LM图以及泥石流发生率与粒度分布图,从图象的不同角度反映出不同环境下形成沉积物的粒度特征,从而阐明了泥石流的发生、发展、形成机制以及判别沉积环境理论依据。并为及早预防泥石流灾害或预报泥石流的发生提供了信息。
Through the analysis on triangle diagram, scatter diagram, CM diagram, LM diagram, occurrence frequency of debris flow and grain size distribution diagram which are based on the grain size data of debris flow sediments along Baocheng railway, this paper shows that the grain size characteristics of sediments of different environments can be reflected in different angles from the images. So it expounds the mechanism of occurrence, development and for- mation of debris flow and the theory basis for judging deposit en- vironments. It also supplies the information for early prediction and prevention of debris flow.
