Seepage problems with complex seepage control structures are very- common in civil engineering. From the perspective of computational hydraulics, this study- uses fluent software to solve the seepage problem with complex seepage control structures by combining finite volume method and VOF free surface capture technology. The comparison between the example calculation and the experimental data shows that the method has high precision in the calculation of the saturation line and seepage flow of the complex seepage control structure, and it is a fast and feasible numerical calculation method. The effectiveness and robustness of the VOF method for complex seepage control structures are verified by adjusting the size of the drainage structure in complex conditions.
