本文论述了同位素综合示踪探测管涌的原理与方法 ,通过对北江大堤石角段管涌区附近钻孔中渗透流速、渗透系数等参数的测定 ,结合理论计算与相关分析推断出该区的管涌来自深部砂岩的断层等构造 ,通过在堤坝顶部钻孔发现了多个空洞构造 ,证实了同位素示踪试验结果的准确性
In this paper, the principle and method of comprehensive tracing of pipelines by isotopes are discussed. By measuring the parameters of seepage velocity and permeability coefficient in the borehole around the Shijiao section of the Beijiang Dyke, combined with theoretical calculation and correlation analysis, Deep sandstone faults and other structures, discovered a number of hollow structures by drilling the top of the dam, confirming the accuracy of the isotope trace test results
