摘要： 为揭示复杂地质条件下缅甸滚弄水电站坝基渗流特征,确定帷幕-排水孔组成的渗控结构的合理布置,构建了精细地质与工程结构模型,采用三维有限元分析对坝基防渗帷幕深度、左右岸防渗帷幕长度、坝基排水深度以及帷幕、固结灌浆区、坝基附近地层、断层抗渗性能等对渗流场的影响进行了详细的敏感性计算分析,绘制了渗流水头等值线图和水力梯度等值线图以及敏感性变化曲线和列表数据,对枢纽区的渗流场变化规律和特点有了深入的认识,为缅甸滚弄水电站坝基渗控结构优化提供了支撑。

Abstract: In order to reveal the seepage characteristics of the dam foundation of Kunlong hydropower station in Myanmar under complex geological conditions,and determine the reasonable layout of the seepage control junction composed of curtain and drainage holes,a fine geological and engineering structure model is established.The three-dimensional finite element analysis is used to analyze the depth of antiseepage curtain of dam foundation,the length of anti-seepage curtain on left and right banks,drainage depth of dam foundation,curtain,consolidation grouting area,strata and faults near the dam foundation.The influence of impermeability on seepage field is calculated and analyzed in detail.The contour maps of seepage head,hydraulic gradient and sensitivity change curve and tabulated data are drawn.The variation law and characteristics of seepage field in the junction area are deeply understood,which provides support for the optimization of seepage control structure of Kunlong hydropower station dam foundation in Myanmar.

Key words: Kunlong hydropower station, seepage analysis, seepage control, anti-seepage curtain, drain holes
