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.
