摘要
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的承载力。通过锚杆质量动测法的试验 ,就锚杆承载力的灰色系统预测方法进行了讨论 ,并与锚杆抗拔检测结果进行了对比。运用灰色系统的锚杆质量检测可取得良好的效果。
Sonoprobe method has been applied in non destructive inspection of anchorage project. Its fundament is using dynamic transient excitation to cause bolt's elastic vibration and the bearing capacity can be estimated or deduced by determining transient response. Based on dynamic test of bolt quality, the forecast means for bolt bearing capacity using gray system is discussed. The result is compared with static state test. It shows, that the quality inspection using gray system proved efficient.
