莲花水电站帷幕轴线位于趾板中部；其中已灌部位处于基岩强风化带下部和弱风化带上部。为保证灌浆质量，施工后对已灌部位进行了质量检测。检测结果表明，经过固结灌浆和帷幕灌浆，在基础有效深度内只存在弱透水带和微透水带，透水率小于３Ｌｕ，满足设计要求，平均渗透坡降计算结果表明，面板下游以堆石为骨架的填料是良好排水体，不会产生渗透稳定问题。
The curtain axis of Lianhua Hydropower Station is located in the middle of the toe plate, of which the irrigated parts are located at the lower part of strong bedrock belt and the upper part of weakly weathered belt. In order to ensure the quality of grouting, the quality of the filling site has been checked after construction. The test results show that only the weak permeable zone and the micro-permeable zone are within the effective depth of foundation after consolidation grouting and curtain grouting. The water permeability is less than 3 Lu, which meets the design requirements. The calculation results of average seepage gradient show that the rockfill is Skeleton filler is a good drainage body, will not produce osmotic stability problems.
