四川省石棉县“7·4"特大泥石流堆积物粒度分布及结构分维
Grain-size Distribution and Structural Dimension of "7 · 4" Giant Debris-flow Deposition in Shimian County, Sichuan Province
摘要
Abstract
The Grain-size distribution and structural dimension analysis of the accumulation zone of the debris flow was accomplished with the graphic method and fractal theory.Results show that the giant debris flow deposits in Hou gully,Xiongjia gully and Majingzi gully are bad sorting,very bad sorting,and very bad sorting,and the components mainly consist of deposit coarse grain.According to fractal theory,it can be known that those three giant debris flow gullies are viscous,and their grain sizes are non-uni-form.Results show that comprehensive utilization of grain-size distribution and structural dimension analysis could understand sorting,grain-size distribution and type of "7 · 4" giant debris-flow deposits very well.It also can provide reference data to formation,movement,accumulation characteristics,numerical simulation,etc.关键词
