Numerical Analysis of the Seepage Field in Core-Dam
The analysis of the seepage field of dam is important to the safety and stability evaluation. Numerical simulation method is adopted in this paper to analyse the seepage field, and through the comparison of the seepage field under different conditions the effect of the core and other factors would be clear. Based on the permeation fluid mechanics, the steady model and transient model are established by using the finite element software Seep/W. Firstly the effect of the core to the seepage of dam is discussed in the steady analysis, then the variation of the upstream water level and the permeability coefficient are discussed in the subsequent transient analysis, which are measured by the hydraulic head, pressure head and velocity of the infiltration. These analysis could guide the design of the dam, provide a strong measurement to the stability and safety.
