Abstract:

A seepage simulation is focused on clay core-rock fill dam all the time. In this study, Putrajaya dam is taken as a case study, the saturated stable seepage computation model was used to analyse Putrajaya dam seepage problem. Two-dimensional finite element model of the clay core-rock fill dam was established by the GeoSlope/SEEPW Software. The numerical simulation computation was carried on dam seepage situation under different conditions. A proposed model is describing the flow pattern and seepage behaviour through the dam. The flow is assumed to be two-dimensional and under steady-state condition. The non-linear differential equation governing the flow is solved using an iterative finite element scheme. The finite element formulation is computer-implemented into a flexible computer program called SEEPW. The results show that the seepage amount through the dam was equal to 3.5620 x 10-8m3 /sec.
