Refer to the impacting-echo technology, we impacted the apex of the steel bar and incepted the reflecting stress \\ave through the resonator that fixed on the apex of the steel bar, and the value of the consolidating wave speed was calculated based on the timeof stress wave transmitted and the length of the steel bar, so, identifying the reflecting signal is the key of the consolidating wave speed method.
借鉴于冲击回波技术，固结波速的测定方法是在钢筋测杆的出露端施加瞬态冲击载荷，由安设在测杆顶端的传感器接收反射应力波信号，根据应力波的走时和测杆的长度折算固结波速的大小，因此反射信号的识别是固结波速法检测混凝土强度的技术关键。
