| 摘 要： | 在实验室模型槽中进行了有悬挂式防渗墙以及堤后压渗盖重的渗流模型试验，取得了不同贯入度以及不同堤后压渗盖重宽度防止堤基渗透变形的系列试验成果。通过一系列试验结果表明，悬挂式防渗墙和堤后压渗盖重可有效地提高强透水层堤基抵抗渗透变形的能力，且在控制渗透变形向上游发展的作用上功效显著。研究表明，堤后压渗盖重的防渗效益往往低于较大贯入度的防渗墙，但从经济角度来看，不失为一种有效可靠的防渗措施。

| Abstract: | The model test on effect of suspended cut-off wall with landside seepage berm on controlling the piping in sandy foundation of levee was carried out in a flume. The experimental results for different suspension depths an different berm width were obtained. It is found that the cut-off wall and landside seepage berm can effectively block the seepage deformation and control the development of piping when the seepage happened. There is a conclusion that landside seepage berm is not less effective than suspended cut-off wall in big degree of penetration, but is a reliable anti-seepage measure from economy aspect. |
