乌江渡水电站地质条件复杂,喀斯特地区岩溶裂隙发育,防渗工程处理量巨大且存在较大难度。为加强防渗效果,采取了混凝土防渗墙、固结灌浆,封堵处理等一系列措施。文中结合近30年的渗漏实测资料,分析了渗漏的变化规律和工作性态。结果显示,工程处理是成功的,有效保证了大坝的安全运行。 The geological conditions of Wujiangdu Hydropower Station are complex, karst fissures are developed in karst area, and the seepage control project has huge capacity and great difficulty. In order to enhance the anti-seepage effect, a series of measures such as concrete cutoff wall, consolidation grouting and plugging treatment have been taken. Based on the measured data of seepage in the past 30 years, the variation regularity and working behavior of seepage were analyzed. The results show that the engineering treatment is successful and effectively ensures the safe operation of the dam.
