摘要：Today, water requirements are not analogously with its availability. Therefore, build water reservoir dam is one of the simple concepts for fulfilling water requirements. Embankment dam is one of the most popular dam build in Indonesia. Stability of embankment dam should be taken into account to evaluate the safety condition in retaining water. Safety against seepage is one of the most important steps for checking the possibility of failure of embankment dam. PLAXIS is alternative software that can be used for evaluating safety of embankment dam due to seepage condition. This paper explains the study of pore water pressure and seepage effects against Sermo Dam safety using PLAXIS and compares it with field measurement data from piezometer and V-Notch monitoring. The study was conducted during dam operational conditions. The analysis was carried out using Mohr-Coulomb model to calculate discharge of seepage and settlement. The value of pore water pressures within the model, upstream and downstream, positions are then reviewed with the real dam. The results of model analysis shows that the more higher water level within the dam reservoir the more higher pore water pressure will be happened that affects in increasing discharge of seepage and settlement of dam.
