Analysis of Dynamic Response of High Rockfill Embankment under Seismic Loads

Abstract:

To reveal the stress-strain properties of Gangou high rockfill embankment with 71m high under seismic loads and provide the reference for its security evaluation and the seismic reinforcement design. By simplifying the high rockfill embankment as the plane problem, establishing two-dimensional finite element model, inputting EL Centro and applying seismic response spectrum method, the dynamic response of high rockfill embankment under seismic loads were simulated. The results show that: With the increase of embankment height, the dynamic response presents increasing tendency; The maximum displacement occurs on the right side of the embankment top, t1474he maximum acceleration appears at the middle of embankment slope. From the view of seismic design, the right side of the embankment top and the middle of embankment slope are the focus of seismic design.
