PFC Simulation on Shaking Table Concrete-Faced Rockfill Dam Model Test
The shape and seismic behavior of concrete-faced rockfill dams under designed seismic load are usually studied by shaking table test, dynamic centrifuge model test and finite element dynamic analysis. Particle flow code (PFC) simulation is analyzed based on the shaking table test, which overcomes the deficiency of macro-continuity assumption in continuum mechanics and can demonstrate the failure characters of dam under dynamic loading action intuitively and vividly. The law obtained from numerical simulation is almost consistent with the one obtained from the shaking table test. The simulation results indicate that the failure characters of concrete-faced rockfill dam are particle sliding on the dam surface and that the concrete face can efficiently reduce the slide displacement and dam top settlement.
