摘要
利用声频应力波法和无损拉拔试验,现场在潘一矿检测了锚杆支护的施工质量,得出声频应力波在锚固体系中的传播、相位和衰减变化规律,以及锚固质量普查检测的分级标准和精确无损测定锚固力的方法。
Based on the inspection of construction quality of bolting by using audiofrequency stress wave and non destructive drawing tests in the First coal Mine of Panyi,principles of propagation,phase and attenuation of andio frequency stress wave in bolting system were drawn.The grading standards of inspection of anchoring quality and a method of precise and non destructive determination of anchoring force are suggested.
