| Abstract: | Based on the analysis of the physical features of site beds, an inhomogeneous and anisotropic steady seepage model is applied to analyze the dyke seepage of Huaihe River during flood periods in both normal segment and the one within subsided section due to underground mining.The finite element modeling method is adopted. With the analytic calculation, the seepage stability of each dyke segment is assessed,and it is considered that the two segments will remain stable. |
