摘要
对高密度电法的工作原理进行了介绍,并应用该方法对龙头石水电站大坝混凝土防渗墙进行检测。通过对检测成果进行分析,推断防渗墙质量较好,仅顶部密实度较差,推断结果与压水等试验结果基本一致。高密度电法能够真实地反映防渗墙混凝土的分布情况,其检测结果明显、直观,便于工程实际应用,具有广阔的应用前景和推广价值。
The principle of high-density resistivity method was introduced in this paper, and the method was used in the detection of concrete anti-seepage wall of Longtoushi hydropower station dam. By analysis on detection result, conclusion was gotten that the quality of anti-seepage wall was generally good, except the compactness at top was low. This was consistent with the result by water pressure test. As high-density resistivity method is of the advantages that it reflects the distribution of anti-seepage wall concrete, its testing result is obvious and it is convenient for engineering application, it has great prospects for application and popularization.
