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。
In this paper, full-wave model phase analysis and instantaneous time-domain spectroscopy method are used to study the kinematic and dynamic characteristics of the elastic wave before and after the concrete pile foundation fracture. A more detailed experimental study of the ultrasonic model is obtained. Under the experimental conditions The criterion for the existence of pile foundation rupture is given and the formula for determining the fracture location is given.
