在锚杆锚固质量检测结果的评定中,指出了平均波速在锚杆锚固质量检测中的重要性。本文通过理论计算得出了砂浆终凝后锚杆锚固体系的平均波速理论值。制作了PVC模型锚杆,在砂浆凝固期间,分别对1、4、8、16、24、48小时采集了模型锚杆数据。经分析处理,得出了6个时刻的平均波速,并且当砂浆达到终凝后得到的实测波速与理论波速相吻合,指出了实际检测工程中存在的问题。 In the evaluation of bolt anchorage quality test results, the importance of average velocity in bolt anchorage quality testing is pointed out. In this paper, the theoretical value of the theoretical average wave velocity of anchoring system after mortar final setting is obtained. The PVC model anchor rod was made. The model anchor rod data were collected for 1, 4, 8, 16, 24 and 48 hours respectively during the setting of the mortar. After analyzing and processing, the average wave velocity at 6 time points is obtained, and the measured wave velocity obtained after the mortar reaches the final setting agrees well with the theoretical wave velocity, pointing out the problems existing in the actual detection engineering.
