Outline of Final Research Achievements

Internal erosion has a certain impact on seismic performance of existing embankment. To evaluate conditions of the embankment before earthquake, deterioration process of soil/geotechnical structure due to seepage flow is needed to be understood. In this research, suffusion is focused on among the various modes of the internal erosion. Physical model tests and numerical simulations are conducted to examine the seepage-induced suffusion process in the embankment. Optical quantification of suffusion in plane strain physical model is successfully made using digital microscope. A plane strain erosion apparatus equipped with microscope observation is developed, which allows detailed observation of the deterioration process and investigation of the mechanical consequences of soils subjected to internal erosion.
