| Abstract | ||
| The injection curtain is assumed to be an effective method for reducing infiltration characteristics, such as flow rate, pore pressure, and outlet gradient across the earthen dam foundation. To investigate the influence and performance of injection curtain, the Izdihar dam is selected as a case study for modeling using the numerical analysis software SEEP/W. The objective of this study is to investigate the injection curtain in terms of different numbers and horizontal spacing between injection curtains. The results revealed that by increasing the horizontal distance between the double curtains from the axis under the central core, the flow rate and the exit gradient are decreased while increasing the horizontal distance, the flow rate is decreased by about 20% and the exit gradient is decreased by about 46%. Similarly, by increasing the distance between double curtains to X/L core =1, the pore pressure is decreased below the dam. Increasing the number of curtains to three is important for minimizing the outlet gradient and flow rate to optimize the safety of the earth dam, the exit gradient decreases up to 21% and flow rate up to 17%, respectively | ||
