利用同位素示踪探测坝基岩体渗漏在国内外已有成功的先例 ,根据 1998年 9月至 1999年 6月 4次在北江大堤管涌严重的石角段 6+ 5 0 0～ 8+ 0 0 0的同位素示踪探测成果 ,结合该堤段的地质情况 ,详尽地分析了该段存在集中渗漏通道的可能性 ,并对今后的进一步探测研究工作提出建议
According to the precedent that the isotope tracer is used to detect the seepage of rock mass of dam foundation at home and abroad, according to the data of 6+ 500 ~ 8+ 0 0 0 isotope tracer detection results, combined with the geological conditions of the embankment section, a detailed analysis of the possibility of a centralized leak path in this section, and make recommendations for further exploration and research work in the future
