简述采用地质雷达检测水利工程隧洞衬砌质量的原理及方法,结合某水电站引水发电洞实例,介绍了探地雷达探测剖面图的解读方法。实践证明:地质雷达对隧洞混凝土钢筋分布、混凝土厚度及衬砌质量探测效果较好。
The principle and method of using geologic radar to detect the lining quality of water conservancy project are briefly described. Based on the example of water diversion tunnel in a hydropower station, the interpretation method of GPR exploration profile is introduced. Practice has proved that: GPR has a good effect on the distribution of concrete in tunnel, concrete thickness and lining quality.
