Effect of Sheetpile Configuration on Seepage beneath Hydraulic Structures
This paper investigates the influence of various sheetpile configurations on the seepage losses, the uplift force on downstream apron of floor, and the exit gradient at the end toe of the apron. A computer program, utilizing the finite element method and based on the fixed mesh approach, was used to locate the free surface of water. The model was applied to investigate seepage below and around a hydraulic structure. Several configurations of the sheetpile driven under the structure were analyzed. Results showed that when the sheetpile confined the downstream apron of the floor from all sides, it has dramatically reduced the exit gradient. In return, this was accompanied by some increase in the uplift pressure force acting on the structure. Other configurations that needed more sheetpile material had little effect on the uplift force and exit gradient.
