Seepage Behavior for Tidal Dike

The considerations of negative pore pressure is difficult to analyze of the tidal dike as a function of influence of tidal variations, but The nagative pore pressure is ionportant in the stability of soil structures. In this study it is analized free water surface variations total head pore pressure and velocity vector distributions of the tidal dike. The model in this study is tested in the lab. and simulated by the finite element method program used Galerkin residual method. The results of this study obtained that a good picture of total head and pore pressure varitions in the tidal dike as a function of external tidal variations. Also it should be recognize that the free water surface is not a boundary condition but a line that pore pressure is zero.
