| 摘 要： | 对集料的粒径分布、级配、集料总体积、空隙率、表面积等做出相关分析,给定了集料各特征值的具体求法,建立体积分维DV和表面积分维DS之间的关系,并根据级配曲线的走向,按不同分段方式进行比表面积计算对比。结果表明:不同的分段方式对于排水沥青混合料的比表面积确定有很大的影响,在进行比表面积计算时,应按各筛级进行逐级分段计算。 |
| 关 键 词： | 分形 集料比表面积 级配曲线 |

| Abstract: | The solutions of these characteristic properties by analyzing the distribution of different particle sizes,gradation,total volume,void rate,and specific surface area were provided,and then the relationship of volume fractal dimension(DV) and surface area fractal dimension(DS) was put forward.According to the tendency of grading curve,specific surface area could be calculated by different grading sections separately.The result presents that the value of surface area is affected by different section dividing manners greatly;this shows the recommend to calculate specific surface area with different grading sections step by step. |
| Keywords: | fractal theory specific surface grading curve |
