| 摘 要： | 基于分形理论对不同击实能和含水量条件下的粉土状黄土进行粒度分析,研究击实后土体颗粒形状的变化情况和颗粒体积的分形行为。结果表明,击实后的粉土状黄土颗粒体积分布遵循分形规律；在一定含水量条件下,分维值D会随着击实能的增加而减小；当击实能较大时,对土样颗粒造成的形状改变也更为明显；在一定击实能条件下,当土样含水量小于最优含水量时,分维值D随着含水量的增加而减小；当土样含水量大于最优含水量后,分维值D呈现离散性,没有一定的规律。

| Abstract: | The particle distrubutes of compacted silty loess are studied based on the fractal theory in this paper,study the the change of soil particles and the fractal behavior of particle distrubutes of compacted loess.The results show that particle size of compacted loess follow the fractal pattern,Under the condition of a certain moisture content,fractal dimension D decreases with the increase of compacted energy.When the compacted energy is large,soil particle shape change is more intense.Under the condition of a certain compacted energy,fractal dimension D decreases with the increase of water content when the moisture content is Less than or equal to optimal water content,rendering discreteness when the moisture content is greater than optimal water content. |
