Abstract
This paper simulates the piping effect, found levees with large difference in coefficient of permeability within the foundation such as the Gim-po Levee, via centrifuge model test which is a model test. We have also conducted a numerical analysis under the same conditions as the centrifuge model test to compare its results. First, we decided to use the centrifuge model based on the Gim-po Levee, and the tests were executed on a model levee with pore water pressure transducers. We have found that most of the water flows through the permeable layer and causes the piping effect. Via video camera footage, we have found that the piping effect occurred at the toe of the model levee. The characteristic of pressure head distribution, obtained from the pore water pressure transducers, also proves the occurrence of the piping effect. The numerical analysis results also showed the same results as the centrifuge model test. We have simulated the piping effect via centrifuge model test and believe that the centrifuge model test is viable for various tests, predictions and evaluation of the levee problems.
