    摘要:

    岩石声波测试技术应用于锚固工程的无损检测中,其基本原理是采用动力瞬态激振使锚杆引起弹性振动,通过测定锚杆的振动响应来估计和推断锚杆中的缺陷。波动方程的有限元数值解表明,在锚杆灌浆体内部缺陷的探测中可用声速、幅值、波形等声参数作为判断的依据。人工神经网络这类非线性动力学系统运用于该灰色系统的质量预测可取得良好的效果。

    Abstract:

    Sonoprobe method has been applied in non-destructive inspection of anchorage project. Its fundament is to cause anchor bar's elastic vibration by dynamic transient excitation and the flaws of anchor bar can be estimated or deduced by determining the transient response. The numeric solution!of hyperbolic equation by FEA indicates that the deductions should comply with the acoustic parameters such as sound velocity, vibration range, wave shape etc., when inspecting the interior flaws in grouting of anchor bar. As a non-linear dynamic system,"the artificial neural networks dealing with quality inspection of gray system have been proved efficient.
