摘　　要：通过室内实验,制作加压系统研究了碎石材料在堆积高度、加载速度等因素对自组织现象的影响。运用"拱"模型分析了自组织产生的原因。运用Matlab程序进行数据处理,对自组织的荷载波动振幅、位移波动振幅、持续时间、间隔时间做了概率统计分析得出了分布规律。Based on the tests, using self-manufactured press box, the effect of higtht of pile, and speed of load on self-organize phenomenon were studied. The cause of self-organization was analysed by using ＂arch＂ model. Self-organization of the load fluctuations in the amplitude, displacement fluctuations in the amplitude, duration, the interval time were done in a statistical analysis , as well as the probability distributions were found.

关 键 词：碎石 自组织 波动 振幅
