基于振动波在土中传播与衰减规律以及土的振动蠕变试验研究 ,分析了厂房柱基振动沉降的原因 ,借助有限元法定量计算出了冲击激励下距振源不同距离处厂房柱基不均匀附加振动应力 ,提出了层状地基上厂房柱基振动沉降的定量计算方法和计算公式 ,为是否需要进行地基处理以及是否需要采取隔振措施提供参考。 Based on the law of vibration propagation and attenuation in soil and the vibration creep test of soil, the reason of vibration settlement of the pillars of the plant was analyzed. The finite element method was used to quantitatively calculate the influence of vibration excitation on the pillars at different distances from the vibration source This paper presents the quantitative calculation method and calculation formula for the vibration settlement of the pillars on the layered foundation. It provides a reference for whether the foundation treatment is needed or whether the vibration isolation measures need to be taken.
