本文简要介绍了凤台电厂引水工程堤防截渗墙的概况及检测方法基本原理,对于检测不合格的截渗墙,进行了重做截渗墙补救,并采用同样的检测技术进行质量检测,验证补救墙是合格的,为工程建设的可靠性提供了依据。对资料进行分析对比发现电反射系数K剖面法、电位电极测深法应用于截渗墙检测取得了良好效果,证明该方法的有效性及可行性。 This paper briefly introduces the general situation of embankment cutoff wall of the diversion project in Fengtai Power Plant and the basic principle of the detection method. For the cut-off wall that failed detection, reworked cutoff wall is rehabilitated, and the same detection technique is used for quality inspection and verification The remedial wall is qualified and provides the basis for the reliability of the construction. Analysis and comparison of the data found that the electrical reflection coefficient K profile method, potential electrode sounding method applied to the cutoff wall detection achieved good results, and proved the effectiveness and feasibility of the method.
