Study on Seepage Stability of Hydraulic Engineering Cut-off Wall Based on Fluid-Structure Coupling Theory
In order to study the law of internal force and deformation of anti-seepage wall of dam body under the coupling of seepage field and stress field,based on the ABAQUS numerical finite element method,the similarities and differences of stress and deformation of the dam cut-off wall under the coupling algorithm and the non-coupling algorithm are studied in this paper,the distribution characteristics of the maximum principal stress in the coupled and uncoupled cases are basically the same,both increase with the depth,and the horizontal displacement increases with the elevation.In general,the displacement obtained by the coupling algorithm is smaller than that by the uncoupling algorithm.The results of this study can be used as a reference for the selection of hydraulic engineering calculation methods.
