摘　　要：为研究矩阵化水库运行管理体系建设背景下,赣州石壁坑水库渗漏对库区流电场的影响,采用拟流场法开展了渗漏口大小、形状的影响性分析。研究表明,圆形渗漏口大小不会影响坝体电流密度分布特征,但渗漏口越大,则电流密度越高。在圆形渗漏口直径不超过1.6m时,电导率的时序演变曲线上没有加速增长阶段。矩形渗漏口大小不同,坝体电流密度变化各异,且矩形渗漏口的长宽比越大,库区电场非平衡性越加剧。电场微观特征可作为库区渗漏分析的参考指标,矩阵化水库运行管理体系可将此纳入监测指标。To investigate the impact of leakage on the flow and electric field in the reservoir area of Ganzhou Shibikeng Reservoir under the context of developing a matrix-based reservoir operation and management system,the quasi-flow field method was used to analyze the influence of the size and shape of leakage points.The study revealed that the size of circular leakage points does not affect the distribution characteristics of current density in the dam body,but larger leakage points result in higher current density.When the diameter of circular leakage points does not exceed 1.6m,the time-series evolution curve of conductivity shows no accelerated growth phase.For rectangular leakage points,variations in size lead to different changes in the dam body’s current density,and the greater the aspect ratio of the rectangular leakage point,the more pronounced the imbalance in the electric field of the reservoir area.The microscopic characteristics of the electric field can serve as reference indicators for reservoir leakage analysis,and the matrix-based reservoir operation and management system can incorporate these as monitoring metrics.
