초록
The aim of this study is to examine the behavior of reservoir fill dam with the water level raising by use of the centrifugalmodel test and the numerical simulation. In this study, LIQCA2D-SF based on the cyclic elasto-plastic constitutive model proposedby Oka et al. (1999) is applied for numerical simulation. In order to investigate the displacements and the pore water pressures inthe fill dam due to the water level raising velocity, three model tests in centrifugal field of 50g for fill dams were conducted. Acomparison between the test result and the simulation result has provided the influence on the displacement and the pore waterpressure of the fill dam with increasing up of the water level.
