【摘要】 基于长期从事水工建筑物渗漏、管涌等安全隐患检测工作的需要,结合水工建筑物渗漏管涌隐患分布的特点,对水底及水体中的电场分布进行了分析研究.本文从水流场与电流场的相似性、渗流场与电流场的相似性以及动态导体充电法的相关理论三个方面阐述了流场法理论的客观性、合理性以及与动态导体充电法理论的兼容性.首先利用水流场与电流场的相似性解释异常水流场,其次从渗流场与电流场的相似性解释异常水流场,最后利用水工建筑物堤坝渗漏管涌通道地电模型,进一步论述了利用地下动态导体充电法中的不等位导体理论来认识流场法理论更为方便,并可以进行渗漏出口处的电流强度计算及进行正反演计算,同时证明了异常水流场与电流场有着近似的对应关系,以工程实例介绍了流场法在水工建筑物渗漏管涌检测中的应用.更多还原

【Abstract】 Based on the needs of detecting long-term leakage in hydraulic structures,piping and other safety hazards,combining with the distribution characteristics of piping risk,the author analyzes the electric field distribution of underwater.From the similarities of the flow field and the current field,seepage field and current field and relevant theories of dynamic conductor charging law,the paper elaborates on the objectivity,rationality of the flow-field theory and the compatibility of the dynamic conductor charging law.After abnormal flow field is interpreted according to the similarities of the flow field and the current field,and the similarities of the seepage field and the current field,the paper,using the geoelectric model of hydraulic structures dam seepage piping channel,discusses that the use of allelic conductor theory in underground dynamic conductor charging method to understand the flow-field theory is more convenient and current intensity and the inversion calculation can be achieved at the leakage exit.Also similar correspondent relationship between the abnormal flow field and current field is proved and application of flow-field method in detecting hydraulic structures leakage is introduced.更多还原
