| Abstract: | A simulation experiment was conducted to examine the occurrence and development of seepage deformation under the effect of the suspended cut-off wall in the two-layer foundation of a levee.The critical head,failure head,seepage discharge,and characteristics of seepage deformation in the study area were obtained by changing the depth into the permeable layer for the plastic drainage plate and simulating the influence of the depth of exposure of the permeable layer in the riverbed on the seepage control effec... |
