Seismic Design of Embankments in Consideration of Damage Process during Earthquakes

抄録

Centrifuge shaking table tests were conducted to evaluate damage level of embankments before sliding failure. In the test series, high-resolution digital images of the model embankments were obtained and strain distributions inside the embankments were calculated using a PIV technique. Results showed that the level of damage in embankment before sliding failure can be evaluated from the level of damage in embankment material near its toe using a stress-strain relationship of embankment material. Finally, we propose a performance verification method for embankments based on the level of damage in embankment material.
