Abstract
In the present study, by simulating an experimental model of a coastal dike (8 m long, 1 m deep and 1 m wide) by FLAC-2D software based on finite difference method, the soil failure mechanism caused by seepage force has been performed. To solve this problem in order to study the boiling, the soil foundation should be analyzed at the most critical condition. The numerical model presented in FLAC-2D is properly able to simulate the flow properties (flow velocity, hydraulic conductivity and seepage discharge). Comparing the results from the numerical model with experimental data shows that the numerical model well predict soil behavior including boiling and soil displacements based on stress–strain analysis. The simulation indicated that dilation and internal friction angles also influenced the stability coefficient.
