花岗岩风化残积物粒度分维特征分析
摘要:对厦门某场地花岗岩风化残积物的粒度分布分析结果表明:花岗岩风化残积物粒度分布具分形特征,风化程度越高,粒度分维越大;粒度分维反映颗粒粗细、颗粒级配,粒度分维可以作为划分风化带和评价力学性质、渗透性的一个指标。
Abstract:Taking a engineering site in Xiamen for example, the distributed granularity of the weathered residual granite is studied. The result shows that it has the character of fractal dimension, the higher degree of weathering, the bigger fractal dimension and the fractal dimension could reflect the grain thickness and the distributed gradation. In the end, the fractal dimension of granularity could be used to be as an index to plot the weathered strip and evaluate mechanical property and permeability.
