| 摘 要： | 针对工程实践中出现的问题,将打入桩的自由段简化为入土端嵌固、锤击端简支的压杆模型,建立桩的振动微分方程,研究锤击轴向力对桩振动频率的影响,并对比锤击初阶频率与桩振动基频的关系得出锤击作用引起柔性桩共振的规律,提出了避开共振影响范围,解决现场工程问题的方法.

| Abstract: | The free part of a driven pile is studied as a column with rigid bottom and simple fixed top. With the nonlinear lateral vibration differential equation of driven pile, the relationship between axial force and vibration frequency is uncovered. Comparing the pile vibration frequency and hammer driving frequency, the resonance frequency domain is obtained, which providing an effective method to solve practice problems by avoiding the resonance frequency domain. |
