摘要
为了较好地模拟现场压实情况,研究了静面压力和振动频率对千枚岩路基填料压实效果的影响规律,提出了合理的振动压实参数;分析了压实度和压实方式对千枚岩路基填料物理力学特性的影响规律,结合千枚岩路基压实现场特性,提出了合理的振动压实时间。通过压实试验,得到了千枚岩路基填料振动压实特性的相关结论。
In order to better simulate the scene compaction situation,the influence law of the static pressure and vibration frequency on the compaction effect of phyllite subgrade filling is studied,the reasonable vibration compaction parameters are put forward;the influence law of the compaction degree and compaction mode on the physical and mechanical properties of phyllite subgrade filling is analyzed and the reasonable vibration time is put forward combining with the phyllite subgrade compaction field characteristics.The conclusion on vibration compaction characteristics of phyllite subgrade filling is obtained by compaction test.
