Non-destructive testing numerical simulation of anchor system based on dynamic response

Numerical simulation is used widely in the field of geotechnical engineering, the paper used finite difference software FLAC3D to numerical simulate status of anchorage system, according to setting different material parameters grouting to simulate different defect in the anchor system. Numerical simulation of anchorage system in the case of characteristic frequency and typical vibration loading are carried out, it was found that the stress wave decaying with the excitation frequency and the vibration loading increases when the stress wave spread in the process of anchoring system.
