水泥搅拌桩在水库大坝除险加固中的应用

水泥土搅拌桩防渗墙作为一种常用的垂直防渗技术,广泛应用于水库大坝除险加固中。采用有限元模拟分析防渗墙布设位置和入土深度对防渗效果的影响。结果表明:防渗墙的设置能够提高大坝的防渗能力;渗流量随着防渗墙向下游移动逐渐提高,随着墙体入土深度的增加逐渐降低;为了便于施工,在坝体中部接近上游位置处布设防渗墙比较合理,不会对防渗效果造成较大影响。研究结果为大坝防渗加固提供参考。
Application of Cement-soil Mixing Pile in Reservoir Dam Reinforcement
As a common vertical anti-seepage technology,the cement-soil mixing pile anti-seepage wall is widely used in the reservoir dam reinforcement.In this paper,finite element simulation is used to analyze the effect of the location and depth of the cut-off wall on the anti-seepage effect.The results show that the cut-off wall can improve the anti-seepage ability of the dam,the seepage rate increases with the movement of the cut-off wall downstream and decreases with the increase of the depth of the wall,it is reasonable to lay cut-off wall in the middle of dam body near upstream,which will not affect the effect of cut-off.The research results provide a reference for dam seepage control and reinforcement.
