摘要

试验模拟了基础工程中散体材料换填垫层,运用概率统计方法和随机过程理论,分析了不同的振动时间、频率对不均匀沉降的影响程度。结果表明时间和频率对沉降高度影响显著。并探讨了散体材料不均匀沉降,离析,震动方向三者之间的联系。
The experiment simulated the ground treatment of cushion method using the granular material in the foundational engineering,using probabilistic statistical methods and random process theory,analyzed the influence of various vibration time and various vibration frequency on the settlement.The results demonstrated that both the vibration time and the vibration frequency had notable effect on the settlement.And it discussed the settlement of granular materials,segregation,vibration direction of the link between the above three.
