| 摘要: |
| 根据设计、施工和现场检测资料，分析了株树桥水库钢筋混凝土面板堆石坝严重渗漏的原因．分析结果表明，面板垫层级配不良，过渡层不能起到反滤作用，基础防渗帷幕的截渗效果欠佳，使垫层承担了较大的作用水头而产生了渗透变形，加之坝体周边缝止水受破坏，面板脱空范围过大，使面板破裂、折断，均导致了大坝严重渗漏。 |

| Abstract: |
| The causes for the serious leakage of the reinforced concrete face dam of Zhushuqiao Reservoir are analyzed based on the design, construction and field measured data. Results show that the poorly graded cushion of the facing plate has little filter effect on the transition layer, the effect of the impervious curtain of the foundation is poor. Owing to a big water head, a seepage deformation occurs in the cushion, the sealing devices in the peripheral joints are destroyed, and some facing plates are overhead and break. All this leads to a serious leakage in the dam. |
