| 摘 要： | 堤防隐患探测是保障堤防工程安全运行的重要工作,现有隐患物探方法种类多,各有优势和适用性,难以全面解决各种隐患探测问题。为了提高物探结果解译准确性,基于堤防隐患的导电性、介电特性等地球物理参数,总结当前常用的隐患物探方法及其适用性。通过室内土工试验,建立堤防土体电阻率、介电常数与含水率、密实度的相关关系。结合长江堤防工程实例,分析堤防隐患的物探方法选择、工作测线布置、地质解译及探测效果对比,证明综合物探法通过对堤防进行全方位多层次探测,能提高隐患探测精度,达到准确、高效、经济的目的。研究成果可为堤防隐患探测的准确解译提供试验和理论基础。

| Abstract: | The detection of hidden dangers of embankment plays an important role in guaranteeing the safe operation of levee project. There are various geophysical detection methods for hidden dangers, each having their own advantages and applicability. It is difficult to solve all kinds of hidden danger detection problems by only one method. According to the geophysical parameters such as conductivity and dielectric property, the commonly used geophysical detection methods for hidden dangers of embankment are summarized. Moreover, through laboratory geotechnical tests, the correlation between resistivity, dielectric constant, moisture content and compactness of embankment soil is established, which provides an experimental and theoretical basis for improving the accuracy of geophysical interpretation. With the Yangtze River embankment project as a case study, the selection of geophysical detection methods, the arrangement of survey lines, the geological interpretation and detection effects are analyzed. It is verified that the comprehensive geophysical detection method can improve the detection precision of hidden dangers and achieve the purpose of accuracy, efficiency and economy. |
