摘　　要：阐述了应力波的频率域特征及谐和振动特征,通过多个模型桩及工程桩检测实例说明,基桩倾斜方向及倾斜度大小可通过频率域作出较准确的判定。In this paper, the authors deal with characteristics of the stress waves in the frequency area and the concord vibration. Through analyzing the data of several model piles and engineering piles, it is held that the inclination direction and tilting degree of the pile can be judged accurately on the basis of frequency area analysis.

关 键 词：基桩倾斜 频率域 振幅谱
