摘要/Abstract

摘要： 为研究免共振沉桩过程对地表振动影响，采用密度放大法以消除模型桩弹性模量过大对计算效率的影响，在有限差分软件FLAC^3D中建立了相应的连续振动沉桩模型，并和文献中的现场测试结果进行了比较，分析了激振力幅值和振动频率这两个施工参数对地表振动响应的影响。结果表明：密度放大法可有效提高数值模拟的计算效率，模拟沉桩7.0倍桩径（4.9 m）所需计算时间约为12.0 h，数值结果较好地模拟了现场测试中免共振沉桩的地表振动影响；激振力幅值和振动频率均主要对近场（水平距离为5.0倍桩径范围内）的地表振动有明显影响；临界沉桩深度与地表振动影响峰值相对应，该深度随水平距离先增大后趋于稳定；激振力幅值对临界沉桩深度的改变不明显，振动频率对远场临界沉桩深度则有较明显影响。

Abstract: Aiming to investigate the ground surface vibration during pile driving with resonance-free technology, a continuous vibratory pile driving model was established by using the finite difference program FLAC^3D. The density scaling method was introduced to eliminate the effect of time consuming due to the excessive elastic modulus of the model pile. The numerical results were compared to the field test data in literature, and then the influence of exciting force amplitude and vibrating frequency on ground surface vibration, was investigated. The results show that:The density scaling method can effectively increase the simulation efficiency, in which the calculation time for penetrating simulated 7.0 times pile diameter (4.9 m) is around 12.0 h, and there is an acceptable agreement between the numerical result and the field measurement; Additionally, the ground surface vibrations are influenced by the exciting force amplitude and the vibrating frequency mainly in the near field (horizontal distance less than 5.0 times pile diameter); Corresponding to the peak ground surface vibration, the critical penetration depth increases first with the horizontal distance and then tends to almost a steady value; Compared to the exciting force amplitude, the vibrating frequency can influence the critical penetration depth in the far field.

Key words: resonance-free vibratory pile driving, density scaling method, numerical simulation, FLAC^3D, ground vibration tests
