| Outline of Final Research Achievements |
For the excavation of soil in an area with a high ground water level, sheet piles or diaphragm walls are often used to retain soil and water. Under such conditions, seepage flow occurs through soil, and seepage failure is often a problem. However, with respect to the mechanism of occurrence of seepage failure, there are many unanswered questions. Seepage failure was discussed from a viewpoint of flow conditions such as 1D-, 2D-, 2D-concentrated, axisymmetric, and 3D flows. Seepage failure experiments were conducted under various flow conditions. Analyses of FEM seepage flow and stability against the seepage failure of soil were also carried out. In this study, with respect to the seepage failure of soil in front of sheet piles, the mechanism and non-dimensional formulization of the critical hydraulic head differences were discussed considering some case studies.
