摘要
隧道衬砌属隐蔽工程施工。常规检查手段多以钻孔验证为主,带有随机性、有损性,且较盲目。地质雷达是利用高频脉冲电磁波探测地下介质分布的一种地球物理勘探方法。以北京—化稍营高速公路黄羊山隧道初衬检测为例,阐述地质雷达的原理和工作方式,并通过雷达图像的解析,得出钢拱架、初衬等的图像特点,为同类工程的研究提供参考。
Tunnel lining belongs to concealed work construction.Conventional detection measures are mainly based on drilling for verification,with randomness,prejudice and blindness.Ground probing radar is a method of geophysical exploration to detect the distribution of underground medium using high frequency impulse electromagnetic wave.Taking the detection of Beijing-Huashaoying Highway Huangyangshan tunnel lining for example,this paper describes the principle and working method of ground probing radar,and obtains the image characteristics of steel arch and initial lining through analysis of radar image,which provides a reference for research of the similar engineering.
