Abstract:According to the basic theory of the saturated - non- Based on the analysis of Wutagou floodway project, 3-D

saturated unsteady seepage field, the finite element model of unstable seepage finite element model is applied to calculate
Wutagou floodway is built by using the equivalent continuum the unstable seepage field of the floodway at flood period. Its
model to analyze seepage characteristics and seepage failure seepage characteristic and the change rule are analyzed, and the
conditions of the embankment and the surrounding soil. Cut-off plan of seepage control measure is determined.

other seepage control measures pared, and the seepage
characteristics of embankment and the surrounding soil are II. FINITE ELEMENT MODEL
analyzed by using the seepage control measures. The results
show that the subsoil water level of both floodway banks is high Finite element grid
