摘要
根据分形理论,以西藏樟木滑坡群为例,详细分析了滑坡活动时空结构的信息维特征和滑动带土粒度分布的分形结构特征。结果表明,滑坡活动具有很好的分形现象;滑动带土的粒度分维值一般在2~3之间,其平均值约为2.8,分维可作为描述滑动带土粒度成分的参数。在此基础上。
Taking Zhangmu landslides group of Tibet as an example, the authors of this paper analysed the features of temporal and spatial structure of landslide activities and the fractal structure of granulometric composition of slipped zone soil based on fractal theory. The results show that landslide activities had a significant fractal phenomenon. The fractal dimensions of grain size of slipped zone are 2 to 3, and average on about 2.8. The fractal dimension of granulometric composition can be taken as a parameter describing soil granulometric composition of slipped zone. The research significance of fractal dimension are also discussed.
