都显示锚杆中锚固段的应力波波速（固结波速）和锚固介质的强度直接相关，固结波速和锚固介质强度之间成抛物线关系。
Numerical simulation results agree with experimental results, both of which show that velocity of consolidation wave in grouted rock bolt are related to the anchoring strength of fresh concrete.
固结波速在混凝土7天龄期内变化尤为显著，这弥补了现有的混凝土无损检测技术不能应用于检测早龄期(特别是7天龄期以前)混凝土强度这一空白。
The consolidating wave speed changes distinctly in 7 days, so it makes up the loss that in being non-destructive testing technology couldn't be used to test the fresh concrete strength.
