地质雷达技术在坝基探测中的应用研究

On application of geological radar in dam foundation detect

应用地质雷达技术在山西省五台县境内的西龙池抽水蓄能电站下库区进行了地质勘探,对勘探技术和方法进行了介绍。勘探前,通过试验比较确定了工作参数,通过地质雷达探测,获取了地质雷达图像,对地层中土质透镜体、碎石架空层等的雷达图像进行了分析。从地质雷达图像中,可以直观地观察至土质透镜体、碎石土架空层等。对地质雷达勘探技术的优缺点进行了分析总结。

The geologic reconnaissance in the lower reservoir area of Xilongchi pumped-storage power station in Wutai county of Shanxi province was carried out by geologic radar technology. This paper presents the reconnaissance technology and method. Before reconnaissance, the reconnaissance parameters were determined through testing and comparison. The geologic radar image was obtained through geologic radar detecting to analyze the radar images of soil lens mass, debris hollow area etc. From the geologic radar image, the soil lens mass, debris hollow area can be observed directly. The advantage and disadvantage of geologic radar reconnaissance technology is analyzed and summarized.
