SYNCHRONIZATION OF HTW PEAK RESPONSES WITH PEAK GROUND ACCELERATION

摘要

Pseudo-static analysis of seismic performance of an earth structure bases on the assumption of the synchronization of its peak responses with the peak ground acceleration. For a mechanically stabilized earth retaining wall, the acceleration, horizontal wall displacement, earth pressure, bearing pressure, and inclusion stresses depict its seismic response. Nonlinear finite analyses performed on a 10-m HTW wall show that all above responses peak synchronistically with the peak horizontal ground acceleration except the bearing pressure under simultaneous horizontal and vertical ground shakings.
