WebMay 6, 2024 · Seismic earth pressure value and its distribution along the wall surface has always been of concern for: (1) the estimation of seismic bearing capacity of shallow foundation in case of skirt foundations and well foundation; (2) analysis of plate and block anchors; and (3) calculation of forces on bridge abutments and earth retaining structures. WebAlso in seismic conditions, active earth pressure coefficients obtained using the M-O method and the limit analysis theorems are in close agreement since the log-spiral failure curves obtained by limit analysis are almost planar (Chen & Liu [8]). Planar failure surfaces were also observed in dynamic model tests
