摘要: 本文采用全波模型震相分析法和时间域的瞬时波谱分析法,对弹性波在混凝土桩基断裂前后的运动学、动力学特征,作了较为详细的超声模型实验研究,获得了实验条件下桩基断裂存在的判据,给出了确定断裂位置的计算公式。

Abstract: Using full-wave model phase analysis and instantaneous spectrum analysis in the time domain, moro detailed studies of the ultrasonic model tests were carried out to get the features of the elastic wave motion and dynamics before and after the break of concrete foundation piles, thus obtaining the data about broken foundation piles under testing condition, giving the formulas for locating the places of break.
