探地雷达技术在堤坝工程中的应用

Application of Radar Detector Technique in Dykes and Dams

堤坝隐患在一定的水文、地质条件下 ,导致倒塌等灾害现象 ,后果不堪设想。当前有关部门正在不断努力探索检测堤坝隐患的新方法、新技术。通过探地雷达检测基本原理、探地雷达开展堤坝检测的物性前提、探地雷达在堤坝工程检测中应用实例 ,说明探地雷达对不同现象堤坝隐患的检测效果。

WT5”BZ]In special hydrological and geological conditions, the natural hazards such as subsidence can be caused by hidden troubles in engineering construction. The radar detector can be used to find out hidden problems in the highway, subsidence areas and dykes and dams. As an advanced shallow exploration equipment, the detecting radar is worked by high frequency microelectronics and computer. The author explains the basic principle of the detector, geophysical prerequisites and application examples for the testing of dykes and dams. Construction examples show that the precision of radar detector is more reliable than that of other methods in concerned conditions. The application of the method should be combined with other exploration methods in the engineering of some comprehensive sites and should be further developed and extended in broad fields. [WT5HZ]
