A STUDY OF RELATIONSHIP BETWEEN COLLAPSIBILITY OF LCOESS AND ITS FRACTAL CHARACTER OF PORE STRUCTURE
-
摘要: 根据已有的资料,探讨了黄土孔隙结构的分形特征,定义了分形特征孔隙半径r2,讨论了分形特征与湿陷性的关系。结果表明,分形特征半径r:与湿陷性具有良好的线性关系,分维值Dx可以反映黄土剖面的成土地质年代。Abstract: On the basis of publicized data, the fractal chracter of pore structure in loess is studied, are also deter-mined fractal characteristic pore radius r2 and discussed relationship between fractal character values and collapsi-bility,results show that there are a good liner relatiouship between r2 and collapsibility, and fractal dimension D2 can reflected geological age of loess section.
