本文介绍了包括自然电场法、伪随机流场拟合法在内的多种物探方法在云南某水电站大坝渗漏检测中的应用情况。通过选择两种或两种以上物探方法在水库大坝渗漏探测上的应用,充分发挥了各种物探方法的优势,取长补短、相互验证,从而提高了物探成果的可靠性和准确性,并通过对现场地质、水位观测资料的大量收集分析,为最终物探成果的综合解释提供了强有力的依据。本文总结了综合物探方法在水库大坝渗漏探测中的应用经验,初步探讨了综合物探方法与单一物探方法相比具有的优点。
This paper introduces the application of multiple geophysical methods including natural electric field method and pseudorandom flow field fitting method in the dam leakage detection of a hydropower station in Yunnan Province. Through the application of two or more geophysical methods in the reservoir dam leakage detection, the advantages of various geophysical methods are fully exerted, and the mutual recognition of the strengths and weaknesses of the geophysical methods is used to improve the reliability and accuracy of the geophysical exploration results. The collection and analysis of on-site geological and water level observation data provide a strong basis for the comprehensive interpretation of the final geophysical achievements. This paper summarizes the application of integrated geophysical methods in the reservoir dam leakage detection, and explores the advantages of the integrated geophysical methods in comparison with a single geophysical prospecting method.
