| 摘 要： | 通过砂槽模型模拟了渗透变形发生和扩展过程，结果说明悬挂式防渗墙对渗透变形的发生条件影响很小，但对渗透变形的扩展及模型破坏的条件影响显著，一方面证实了悬挂式防渗墙渗流控制效果不显著这一已有的结论，另一方面证明了悬挂式防渗墙在一定条件下对险情的扩展可以起到控制作用。

| Abstract: | The development of seepage deformation is animated with model test in sandbox. The results indicate that the imperivious wall of suspension type will not significantly affect the occurrence of seepage deformation, but it influences seepage deformation propagation remarkbly. It verifies that the impervious wall of suspension type is not effective in seepage control but is useful for controlling the development of seepage deformation. |
