摘　　要：水布垭面板堆石坝的面板脱空检测主要采用地质雷达普查和缺陷部位加密详查,声波垂直反射法对已确定缺陷的部位进行复查,这两种方法从不同角度反映面板脱空的状态,相互验证,提高了面板脱空检测成果的准确性,取得了良好的检测效果[1]。In Shuibuya Hydropower Station,geological radar is adopted to generally examine the face slab void of the concrete face rockfill dam and densely investigate the possible void locations.Acoustic vertical reflection method is adopted to re-check the identified void locations.These two methods can reflect the void status of the face slab from different angles and the findings can be verified mutually,which improves the detection accuracy of the face slab void and achieves satisfactory performance.
