| 摘 要： | 从分形几何的观点出发，通过对冻土模型的爆破试验，着重对试样爆后破块块度分析进行了统计分析。结果表明，冻土爆后块度分布是个分形，分形维数不仅是反映冻土破碎程度恰当的统计特征量，而且与试样冻结温度密切相关，还探讨了分维值与冻土抗压强度的关系。

| Abstract: | In this paper, according to the point of view of fractal geometry, the size-frequency distribution of fragments is analysed statistically by model blasting tests in frozen soil. The result shows that the size-frequency distribution is a fractal, and the fractal dimension is not only an appropriate parametar which indicates the degree of fragmentation of frozen soil, but also related closely to temperature in frozen soil samples. In addition, the relationship between the compressive strength of frozen soil samples and fractal dimension is inquired. |
