Application of geological radar in tunnel lining quality examination

简述地质雷达在隧洞衬砌质量检测中的原理及方法,结合工程实例将地质雷达与钻芯验证相结合,对隧洞衬砌厚度、钢筋分布检测结果进行对比分析,并将成果应用于多座水库隧洞衬砌的质量检测,结果表明:地质雷达对隧洞混凝土钢筋分布、混凝土厚度及衬砌情况探测效果较好。

A brief introduction was made on the principle and method of applying geological radar in tunnel lining quality examination. For an actual project, geological radar was used to examine the tunnel lining thickness and re- inforcing steel distribution, and the examination results were checked by core drill. The achievements of comparison and analysis were applied in tunnel lining quality examination of multiple reservoir projects. The results of application demonstrate that geological radar renders good effects for examination of tunnel reinforcing bar distribution, concrete thickness and lining quality.
