摘要
以麻崖子隧道工程为例,采用地质雷达对其锚喷支护进行质量检测,检测结果发现锚喷支护背后存在空洞,在分析产生空洞的原因后,采取注浆补救措施。经雷达检测结果证实,注浆较为密实,加固效果较好。
Taking Mayanzi Tunnel engineering as an example, ground penetrating radar （GPR） was used to carry out quality inspection in relation to the shotcrete-bolt support thereof. As a result, cavities were found in the back of the support. Through analysis of the causes, grouting was adopted as a remedy. After the treatment, it was proved by GPR inspection that the grouting is densified and leads to good reinforcement effect.
