| 摘要: |
| 汤浦混凝土面板堆石坝的地基含有粉质粘土和淤泥质粘土．为加快坝基固结，减少蓄水后坝体沉降量，防止混凝土面板因坝基沉降而产生裂缝，采用振冲碎石桩加固处理地基．蓄水后经原型观测资料验证，坝基的承载力明显提高，混凝土面板运行正常，达到了设计的预期效果． |

| Abstract: |
| There are silty and muddy clays in the foundation of Tangpu concrete face rockfill dam. In order to speed up foundation consolidation, to reduce dam's settlement and to prevent face crack caused by the foundation settlement after storing water, the vibration stone pile technique is applied in the foundation development. The prototype measurement data after storing water show that the foundation's capacity is increased apparently, and that the concrete face is running well to meet the design requirement. |
